Sensitive health-data exposure in the Lenovo Health Android application (distributed exclusively in the Chinese market) stems from hardcoded credentials (CWE-798) that let an attacker access users' health-related information without legitimate authentication. Reported by Lenovo PSIRT and tracked under a single Lenovo advisory, it carries a CVSS 4.0 base of 9.3 driven by high confidentiality impact. No public exploit has been identified at time of analysis, and it is not listed in CISA KEV.
Local privilege escalation in Lenovo Rescue and Smart Assistant (LMSA) enables a local authenticated user to execute arbitrary code with elevated privileges by exploiting a capture-and-replay authentication bypass (CWE-290) in the application's privileged service layer. The vulnerability is strictly local in scope per the CVSS 4.0 vector (AV:L/PR:L), limiting the threat to attackers who already hold a standard user account on an affected Lenovo device. Lenovo has published advisory LEN-217409 with remediation guidance; no public exploit has been identified at time of analysis.
Improper export of Android application components in Lenovo File Manager (Chinese-market distribution) enables a locally authenticated user or co-installed application to read or modify files that the application designates as protected. The root cause is CWE-926, where one or more Android components - likely a content provider or activity - are exported without enforcing the application's own authorization logic. No public exploit code exists and the vulnerability has not been added to CISA KEV; however, the CVSS 4.0 score of 8.4 reflects genuine high-impact file access if an attacker can install a companion malicious application on the target device.
Privilege escalation in the Lenovo Filez Client application allows a local authenticated user to gain elevated system rights via improper file or directory permissions (CWE-276). The CVSS 4.0 score of 8.5 reflects a meaningful local attack path with low complexity and no special attack requirements, though exploitation is bounded by the requirement for an existing local foothold. No active exploitation or public proof-of-concept has been identified at time of analysis.
Privilege escalation via symlink following in Lenovo Vantage and Lenovo Commercial Vantage allows a local authenticated user to execute arbitrary code with elevated privileges on affected Lenovo systems.

Improper TLS certificate validation in multiple Lenovo XClarity Orchestrator (LXCO) 2.2.0 microservices exposes sensitive management communications to interception by an adjacent network attacker capable of positioning themselves for a machine-in-the-middle attack. The flaw (CWE-295) allows the attacker to bypass HTTPS trust enforcement under unspecified triggering circumstances, potentially capturing credentials, tokens, or orchestration data exchanged between LXCO microservices. No public exploit code or CISA KEV listing exists at time of analysis; Lenovo has released a patch via advisory HT509976.
PowerShell command injection in Lenovo XClarity Integrator for Microsoft Windows Admin Center (versions 5.1.1 and below) running on the WAC Gateway allows an authenticated low-privileged attacker to inject arbitrary PowerShell commands when the plugin establishes remote PowerShell sessions. Successful exploitation yields high-impact code execution that extends beyond the plugin into subsequent systems (managed hosts), with full confidentiality, integrity, and availability compromise. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Local privilege escalation to arbitrary code execution affects Lenovo App Store, a software-distribution client shipped exclusively on Lenovo devices in the Chinese market. A local authenticated user who can interact with the application can leverage its excessive privileges (CWE-250) to run arbitrary code at an elevated privilege level, with high confidentiality, integrity, and availability impact on the host. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, so no active exploitation is confirmed.
Local code execution in Lenovo App Store (Chinese-market distribution only) lets an authenticated local user abuse a path traversal weakness to write or load files outside intended directories and run arbitrary code. The flaw was self-reported by Lenovo and carries a CVSS 4.0 base score of 7.0; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. Impact is high to confidentiality, integrity, and availability of the local system, but exploitation requires existing low-privilege local access plus user interaction.
Local code execution in Lenovo Legion Zone and the Lenovo App Store (China-market Windows builds) allows an authenticated local user to run arbitrary code when either application is installed on a non-system partition. The flaw stems from insecure directory/file permissions (CWE-277) that a low-privileged user can abuse to plant or modify executable content later run with higher privilege. No public exploit is identified at time of analysis and it is not listed in CISA KEV; impact is confined to systems where these Chinese-market Lenovo utilities are deployed to a non-default drive.
Local privilege escalation in the FluxInk (formerly Sunia SPB Peripheral) Color Management Driver TcnPeripheral64.sys version 1.0.7.2 lets a standard user map arbitrary physical memory via the \Device\PhysicalMemory object and gain kernel-level control. The flaw affects Lenovo systems shipping this signed color-management driver and is fixed in version 1.0.7.6. Publicly available exploit code exists; there is no public exploit identified as actively exploited (not in CISA KEV), though the vulnerability was reported by CISA (cisa-cg).
Privilege escalation in Lenovo Smart Connect for Windows allows a local authenticated user to bypass authentication checks and execute arbitrary code with elevated privileges. The flaw stems from an authentication bypass weakness (CWE-290) in the Windows client and carries a CVSS 4.0 score of 7.3. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Local privilege escalation in Lenovo's LanSchool Classic client application allows authenticated users on affected endpoints to execute arbitrary code with elevated privileges via an uncontrolled search path (CWE-427). The flaw carries a CVSS 4.0 score of 8.5 with high impact across confidentiality, integrity, and availability, and no public exploit identified at time of analysis. Because LanSchool Classic is widely deployed in K-12 and education environments, exploitation could let a student or low-privileged user gain SYSTEM-level control of managed classroom devices.
Local privilege escalation in Lenovo Accessories and Display Manager for Enterprise on Windows allows an authenticated low-privileged user to execute arbitrary code with elevated privileges, per a Lenovo-disclosed internal finding (LEN-213623). The CVSS 4.0 base score of 8.5 reflects high impact to confidentiality, integrity, and availability of the vulnerable system, though no public exploit identified at time of analysis. The CWE-306 (Missing Authentication for Critical Function) classification combined with the 'Authentication Bypass' tag suggests a privileged operation in the product is reachable without proper access checks.
Out-of-bounds read in the Linux kernel's AppArmor LSM subsystem (security/apparmor/match.c) allows a local low-privileged user to trigger a KASAN slab-out-of-bounds read via the mount() syscall on kernels 7.0 through 7.0.3 and 7.1-rc1. The flaw stems from a missing string terminator that causes aa_dfa_match() to read past the end of an 8KB kmalloc buffer when processing mount path strings, resulting in potential information disclosure and system instability (denial of service). No public exploit identified at time of analysis, and EPSS probability is negligible at 0.02%.
Path traversal in Lenovo Personal Cloud Storage devices allows authenticated remote attackers to move or access files belonging to other users on the same device, enabling unauthorized data disclosure and modification across user boundaries. Affects multiple product lines including Personal Cloud (T1, T2, T2S, T2Pro, X1, X1S, A1, A1S) and Home Storage Hub (T20, X20).

Out-of-bounds memory access in the ELAN TrackPoint device driver on Lenovo ThinkPad and related laptops allows a local authenticated user to crash the operating system under specific conditions, resulting in a denial-of-service. Disclosed by Lenovo via advisory LEN-213604, the vulnerability spans a very large number of ThinkPad model lines running Windows 10 and Windows 11. No public exploit code has been identified and the vulnerability is not listed in CISA's Known Exploited Vulnerabilities catalog, consistent with its local-only, high-complexity attack profile.
Arbitrary file deletion with elevated privileges affects Lenovo Dock Manager across all tracked versions (CPE: cpe:2.3:a:lenovo:dock_manager:*:*:*:*:*:*:*:*). An authenticated local user can exploit this CWE-59 link-following flaw to redirect the application's privileged file deletion routine to arbitrary targets outside the user's permitted scope, threatening both system integrity and availability. The vulnerability was identified through Lenovo's own internal security assessment; a vendor patch is available via advisory LEN-223470, and no public exploit has been identified at time of analysis.
Arbitrary file deletion with elevated privileges is possible in the VantageCoreAddin component of Lenovo Vantage and Lenovo Commercial Vantage via an improper link following (symlink) attack. A local authenticated user operating with low privileges can exploit this to delete files outside their authorized scope by placing a malicious symbolic or hard link in a path the addin traverses with elevated rights. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
In the Linux kernel, the following vulnerability has been resolved: HID: hid-lenovo-go: cancel cfg_setup work in hid_go_cfg_remove() hid_go_cfg_probe() initialises drvdata.go_cfg_setup and schedules it to run 2 ms later: INIT_DELAYED_WORK(&drvdata.go_cfg_setup, &cfg_setup); schedule_delayed_work(&drvdata.go_cfg_setup, msecs_to_jiffies(2)); cfg_setup() dereferences drvdata.hdev to issue MCU command requests. hid_go_cfg_remove() tears down sysfs and stops the HID device, but never drains the delayed work. If the device is unbound within the 2 ms scheduling delay (a probe failure rolling back via remove, or a fast rmmod after probe), the work fires after hid_destroy_device() has dropped its reference and released the underlying hdev struct, leaving cfg_setup() with a stale drvdata.hdev pointer. Mirror the sibling driver hid-lenovo-go-s.c, whose hid_gos_cfg_remove() already calls cancel_delayed_work_sync() on its analogous work, and drain go_cfg_setup at the top of hid_go_cfg_remove(). The cancel must come before guard(mutex)(&drvdata.cfg_mutex) because cfg_setup() acquires that mutex; reversing the order would deadlock.
Insecure temporary file creation in Lenovo XClarity Essentials OneCLI 5.5.0 and earlier on Linux enables a local low-privileged attacker to overwrite or truncate arbitrary system files via a race condition (CWE-377), but only when a privileged user concurrently executes OneCLI with elevated rights. The attack timing requirement (AT:P in the vendor CVSS 4.0 vector) confirms this is a classic TOCTOU-style symlink race, limiting realistic exploitation to shared multi-user Linux environments where an administrator routinely runs the tool elevated. No public exploit code or CISA KEV listing exists; the vendor has released a patch via advisory LEN-ht116433.
Deadlock in the Linux kernel's drm/msm (Qualcomm Snapdragon GPU) shrinker causes full kernel hang under memory reclaim pressure. The circular lock dependency arises when the kswapd0 thread holds fs_reclaim and the MSM gem shrinker calls dma_resv_lock(), which internally attempts to re-acquire fs_reclaim - producing a ABBA deadlock that renders the system unresponsive. Kernels in the affected range on Snapdragon-based hardware (Linux 6.17 through pre-patch 7.0.x and 6.18.x) are vulnerable; no public exploit code exists and no active exploitation has been confirmed.
In the Linux kernel, the following vulnerability has been resolved: platform/x86: lenovo-wmi-helpers: Fix memory leak in lwmi_dev_evaluate_int() lwmi_dev_evaluate_int() leaks output.pointer when retval == NULL (found by sashiko.dev [1]). Fix it by moving `ret_obj = output.pointer' outside of the `if (retval)' block so that it is always freed by the __free cleanup callback. No functional change intended.
Lenovo BIOS firmware across dozens of consumer and gaming laptop models - Legion, IdeaPad, Yoga, ThinkBook, LOQ, and V-series - contains a missing authentication flaw in the WMI-to-SMI interface that permits a local privileged attacker to arbitrarily trigger System Management Interrupt handlers, enabling execution at the SMM firmware level below the operating system security boundary. No public exploit code has been identified at time of analysis, and CISA KEV listing is not confirmed. The practical threat is post-compromise firmware persistence: an attacker already holding OS-level administrative privileges could use this flaw to manipulate firmware behavior in ways invisible to endpoint security tools, bypassing Secure Boot or implanting persistent code in System Management Mode.
Out-of-bounds write in Lenovo BIOS firmware across dozens of consumer and gaming laptop models enables a local attacker with high OS-level privileges to execute arbitrary code in System Management Mode (SMM) - a CPU execution context operating below the operating system and hypervisor with access to all system memory. Successful exploitation allows persistent firmware-level implants that survive OS reinstallation and defeat Secure Boot and standard endpoint detection tools. No public exploit has been identified at time of analysis, and this vulnerability is not listed in CISA KEV; however, SMM code execution represents one of the highest-impact firmware attack primitives available to an advanced threat actor.
SMM memory address disclosure in Lenovo laptop BIOS firmware exposes the location of protected System Management Mode (SMRAM) regions to a local privileged attacker. Dozens of Lenovo consumer, gaming, and business laptop product lines are affected across IdeaPad, Legion, Yoga, ThinkBook, LOQ, and V-series models. While the direct impact is confidentiality-only, SMRAM address disclosure is a classic prerequisite step in firmware-level attack chains that seek to bypass address-space protections and ultimately plant persistent SMM rootkits. No public exploit has been identified at time of analysis, and exploitation is not confirmed in CISA KEV.
Out-of-bounds write in Lenovo BIOS firmware across dozens of consumer and gaming laptop models enables a local privileged attacker to corrupt power management settings within System Management Mode, a CPU execution context operating below the OS kernel at Ring -2. Successful exploitation could allow persistent firmware-level tampering that survives OS reinstalls and reboots. No public exploit has been identified at time of analysis, and exploitation requires pre-existing high OS-level privileges, substantially limiting real-world risk to post-compromise scenarios.
Lenovo Smart Connect for Windows exposes an improper access control flaw that permits a local authenticated user to read files belonging to other users on the same machine. Discovered through Lenovo's own internal security assessment and documented under advisory LEN-218281, the flaw carries a CVSS 4.0 score of 6.8 with a local, low-privilege attack vector and high confidentiality impact. No public exploit code and no CISA KEV listing exist at time of analysis, limiting immediate risk to multi-user Windows environments where Lenovo Smart Connect is installed.
NULL pointer dereference in the Linux kernel's ASoC SDCA (SoundWire Device Class for Audio) subsystem crashes the kernel during audio device cleanup, resulting in a denial of service. The `sdca_dev_unregister_functions()` routine iterates over SDCA function descriptors without validating for NULL entries, which can be present when function registration fails partway through or when device cleanup races with probe deferral. This crash was observed in practice on Lenovo ThinkPad X1 Carbon G14 (Panther Lake) systems where missing SOF firmware caused the SOF audio driver probe to fail, triggering the NULL dereference during subsequent SoundWire device teardown. No public exploit exists and EPSS sits at 0.14% (4th percentile), reflecting the hardware-specific and locally-triggered nature of this flaw.
NULL pointer dereference in the Linux kernel's ps883x USB Type-C retimer driver causes a kernel Oops during device unbind, resulting in a denial of service. The ps883x_retimer_remove() function calls i2c_get_clientdata() to retrieve driver-private state, but i2c_set_clientdata() was never called during probe, leaving the pointer NULL; dereference at offset 0x20 triggers a fatal translation fault. Systems with ps883x retimer hardware running affected kernel versions are vulnerable when a privileged local user unbinds the driver via sysfs. No active exploitation is confirmed (no CISA KEV listing), and the EPSS score of 0.17% (6th percentile) reflects negligible real-world exploitation probability.
Local privilege escalation to System Management Mode (SMM) in Lenovo ThinkPad BIOS firmware allows a high-privileged local user to execute arbitrary code at one of the most privileged execution rings on x86 hardware. The flaw, an out-of-bounds write (CWE-787) discovered by Lenovo during an internal security assessment, affects a wide range of current-generation ThinkPad models including X1 Carbon 13th Gen, X13 Gen 6, T14s Gen 6, P14s/P16v Gen 3, L13/L14/L16 Gen 6, and E16 Gen 3. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Arbitrary privileged memory read/write in Lenovo ThinkPad embedded controller (EC) firmware allows a local administrator on affected ThinkPad models (X13 Gen 6, X1 Carbon 13th Gen, P16v Gen 3, L16 Gen 1/2, T14s Gen 6, P14s Gen 6, L13 Gen 6, L14 Gen 6) to access or modify protected memory regions. Discovered during Lenovo's internal security assessment, the issue is rated CVSS 4.0 8.4 (High) and there is no public exploit identified at time of analysis, with no CISA KEV listing. Despite the high score, exploitation requires high privileges and local access, narrowing realistic abuse to attackers who already have admin on the host or to supply-chain/insider scenarios.
Clipboard hijacking in Lenovo's built-in Android browser application allows a malicious website to silently overwrite system clipboard contents on affected devices. The vulnerability impacts Lenovo Android tablets distributed exclusively in the Chinese market, enabling a network-based attacker to manipulate clipboard data when a user visits a crafted website. No confirmed active exploitation (CISA KEV) or public exploit code has been identified at time of analysis; EPSS data was not provided in available intelligence.
Kernel crash (local denial of service) in the Linux nouveau NVIDIA GPU driver allows a local authenticated user to trigger a kernel WARNING and system instability by accessing the DisplayPort AUX channel (/dev/drm_dp_*) while the GPU is in runtime-suspended state. The driver fails to check device power state before invoking the GSP (GPU System Processor) firmware communication path, causing an unhandled condition in r535_gsp_msgq_wait. No public exploit exists and the EPSS score is 0.02% (7th percentile), but the vulnerability is notable in environments where fwupd or similar firmware tools interact with DP AUX interfaces on systems using the nouveau driver with runtime power management enabled.

We need to generate a JSON object for CVE-2026-1636. All fields must be plain text strings. Use all provided data: EPSS, KEV not mentioned (so not in KEV), tags, CPE, CVSS 4.0 vector, SSVC, etc. First, understand the vulnerability: "potential DLL hijacking vulnerability was reported in Lenovo Service Bridge that, under certain conditions, could allow a local authenticated user to execute code with elevated privileges." CWE-427: Uncontrolled Search Path Element (DLL hijacking). CVSS 4.0: AV:L/AC:L/AT:P/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N. That is local, low attack complexity, Attack Requirements: P (present? AT:P means attack requirements present, maybe specific conditions), Privileges Required: Low, User Interaction: Passive (UI:P means limited user interaction, e.g., user must open a file or perform some action). Impact: High on vulnerable system confidentiality, integrity, availability; no impact on subsequent system. This matches the description: local authenticated user, elevated privileges. The vector indicates PR:L, so authenticated. AT:P suggests there are some attack requirements beyond just running code, like needing to place a DLL in a specific path or something. EPSS 0.01%, percentile 2%, very low exploitation probability. SSVC: exploitation: none, automatable: no, technical impact: total. So not currently exploited, not automatable, total impact if exploited. Patch available, affected versions: Service Bridge 0 <5.0.2.20 (from EUVD). So fix version is 5.0.2.20 or later. Reference: Lenovo advisory LEN-211071. So we have exact patch. Now, fields: product_name: "Lenovo Service Bridge" (3 words) summary: Synthesize a 2-3 sentence plain-language summary, not copying description. Start with impact verb and product.

Arbitrary file deletion with elevated privileges affects Lenovo Dock Manager across all tracked versions (CPE: cpe:2.3:a:lenovo:dock_manager:*:*:*:*:*:*:*:*). An authenticated local user can exploit this CWE-59 link-following flaw to redirect the application's privileged file deletion routine to arbitrary targets outside the user's permitted scope, threatening both system integrity and availability. The vulnerability was identified through Lenovo's own internal security assessment; a vendor patch is available via advisory LEN-223470, and no public exploit has been identified at time of analysis.
Arbitrary file deletion with elevated privileges is possible in the VantageCoreAddin component of Lenovo Vantage and Lenovo Commercial Vantage via an improper link following (symlink) attack. A local authenticated user operating with low privileges can exploit this to delete files outside their authorized scope by placing a malicious symbolic or hard link in a path the addin traverses with elevated rights. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
In the Linux kernel, the following vulnerability has been resolved: HID: hid-lenovo-go: cancel cfg_setup work in hid_go_cfg_remove() hid_go_cfg_probe() initialises drvdata.go_cfg_setup and schedules it to run 2 ms later: INIT_DELAYED_WORK(&drvdata.go_cfg_setup, &cfg_setup); schedule_delayed_work(&drvdata.go_cfg_setup, msecs_to_jiffies(2)); cfg_setup() dereferences drvdata.hdev to issue MCU command requests. hid_go_cfg_remove() tears down sysfs and stops the HID device, but never drains the delayed work. If the device is unbound within the 2 ms scheduling delay (a probe failure rolling back via remove, or a fast rmmod after probe), the work fires after hid_destroy_device() has dropped its reference and released the underlying hdev struct, leaving cfg_setup() with a stale drvdata.hdev pointer. Mirror the sibling driver hid-lenovo-go-s.c, whose hid_gos_cfg_remove() already calls cancel_delayed_work_sync() on its analogous work, and drain go_cfg_setup at the top of hid_go_cfg_remove(). The cancel must come before guard(mutex)(&drvdata.cfg_mutex) because cfg_setup() acquires that mutex; reversing the order would deadlock.
Insecure temporary file creation in Lenovo XClarity Essentials OneCLI 5.5.0 and earlier on Linux enables a local low-privileged attacker to overwrite or truncate arbitrary system files via a race condition (CWE-377), but only when a privileged user concurrently executes OneCLI with elevated rights. The attack timing requirement (AT:P in the vendor CVSS 4.0 vector) confirms this is a classic TOCTOU-style symlink race, limiting realistic exploitation to shared multi-user Linux environments where an administrator routinely runs the tool elevated. No public exploit code or CISA KEV listing exists; the vendor has released a patch via advisory LEN-ht116433.
Deadlock in the Linux kernel's drm/msm (Qualcomm Snapdragon GPU) shrinker causes full kernel hang under memory reclaim pressure. The circular lock dependency arises when the kswapd0 thread holds fs_reclaim and the MSM gem shrinker calls dma_resv_lock(), which internally attempts to re-acquire fs_reclaim - producing a ABBA deadlock that renders the system unresponsive. Kernels in the affected range on Snapdragon-based hardware (Linux 6.17 through pre-patch 7.0.x and 6.18.x) are vulnerable; no public exploit code exists and no active exploitation has been confirmed.
In the Linux kernel, the following vulnerability has been resolved: platform/x86: lenovo-wmi-helpers: Fix memory leak in lwmi_dev_evaluate_int() lwmi_dev_evaluate_int() leaks output.pointer when retval == NULL (found by sashiko.dev [1]). Fix it by moving `ret_obj = output.pointer' outside of the `if (retval)' block so that it is always freed by the __free cleanup callback. No functional change intended.
Lenovo BIOS firmware across dozens of consumer and gaming laptop models - Legion, IdeaPad, Yoga, ThinkBook, LOQ, and V-series - contains a missing authentication flaw in the WMI-to-SMI interface that permits a local privileged attacker to arbitrarily trigger System Management Interrupt handlers, enabling execution at the SMM firmware level below the operating system security boundary. No public exploit code has been identified at time of analysis, and CISA KEV listing is not confirmed. The practical threat is post-compromise firmware persistence: an attacker already holding OS-level administrative privileges could use this flaw to manipulate firmware behavior in ways invisible to endpoint security tools, bypassing Secure Boot or implanting persistent code in System Management Mode.
Out-of-bounds write in Lenovo BIOS firmware across dozens of consumer and gaming laptop models enables a local attacker with high OS-level privileges to execute arbitrary code in System Management Mode (SMM) - a CPU execution context operating below the operating system and hypervisor with access to all system memory. Successful exploitation allows persistent firmware-level implants that survive OS reinstallation and defeat Secure Boot and standard endpoint detection tools. No public exploit has been identified at time of analysis, and this vulnerability is not listed in CISA KEV; however, SMM code execution represents one of the highest-impact firmware attack primitives available to an advanced threat actor.
SMM memory address disclosure in Lenovo laptop BIOS firmware exposes the location of protected System Management Mode (SMRAM) regions to a local privileged attacker. Dozens of Lenovo consumer, gaming, and business laptop product lines are affected across IdeaPad, Legion, Yoga, ThinkBook, LOQ, and V-series models. While the direct impact is confidentiality-only, SMRAM address disclosure is a classic prerequisite step in firmware-level attack chains that seek to bypass address-space protections and ultimately plant persistent SMM rootkits. No public exploit has been identified at time of analysis, and exploitation is not confirmed in CISA KEV.
Out-of-bounds write in Lenovo BIOS firmware across dozens of consumer and gaming laptop models enables a local privileged attacker to corrupt power management settings within System Management Mode, a CPU execution context operating below the OS kernel at Ring -2. Successful exploitation could allow persistent firmware-level tampering that survives OS reinstalls and reboots. No public exploit has been identified at time of analysis, and exploitation requires pre-existing high OS-level privileges, substantially limiting real-world risk to post-compromise scenarios.
Lenovo Smart Connect for Windows exposes an improper access control flaw that permits a local authenticated user to read files belonging to other users on the same machine. Discovered through Lenovo's own internal security assessment and documented under advisory LEN-218281, the flaw carries a CVSS 4.0 score of 6.8 with a local, low-privilege attack vector and high confidentiality impact. No public exploit code and no CISA KEV listing exist at time of analysis, limiting immediate risk to multi-user Windows environments where Lenovo Smart Connect is installed.
NULL pointer dereference in the Linux kernel's ASoC SDCA (SoundWire Device Class for Audio) subsystem crashes the kernel during audio device cleanup, resulting in a denial of service. The `sdca_dev_unregister_functions()` routine iterates over SDCA function descriptors without validating for NULL entries, which can be present when function registration fails partway through or when device cleanup races with probe deferral. This crash was observed in practice on Lenovo ThinkPad X1 Carbon G14 (Panther Lake) systems where missing SOF firmware caused the SOF audio driver probe to fail, triggering the NULL dereference during subsequent SoundWire device teardown. No public exploit exists and EPSS sits at 0.14% (4th percentile), reflecting the hardware-specific and locally-triggered nature of this flaw.
NULL pointer dereference in the Linux kernel's ps883x USB Type-C retimer driver causes a kernel Oops during device unbind, resulting in a denial of service. The ps883x_retimer_remove() function calls i2c_get_clientdata() to retrieve driver-private state, but i2c_set_clientdata() was never called during probe, leaving the pointer NULL; dereference at offset 0x20 triggers a fatal translation fault. Systems with ps883x retimer hardware running affected kernel versions are vulnerable when a privileged local user unbinds the driver via sysfs. No active exploitation is confirmed (no CISA KEV listing), and the EPSS score of 0.17% (6th percentile) reflects negligible real-world exploitation probability.
Local privilege escalation to System Management Mode (SMM) in Lenovo ThinkPad BIOS firmware allows a high-privileged local user to execute arbitrary code at one of the most privileged execution rings on x86 hardware. The flaw, an out-of-bounds write (CWE-787) discovered by Lenovo during an internal security assessment, affects a wide range of current-generation ThinkPad models including X1 Carbon 13th Gen, X13 Gen 6, T14s Gen 6, P14s/P16v Gen 3, L13/L14/L16 Gen 6, and E16 Gen 3. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Arbitrary privileged memory read/write in Lenovo ThinkPad embedded controller (EC) firmware allows a local administrator on affected ThinkPad models (X13 Gen 6, X1 Carbon 13th Gen, P16v Gen 3, L16 Gen 1/2, T14s Gen 6, P14s Gen 6, L13 Gen 6, L14 Gen 6) to access or modify protected memory regions. Discovered during Lenovo's internal security assessment, the issue is rated CVSS 4.0 8.4 (High) and there is no public exploit identified at time of analysis, with no CISA KEV listing. Despite the high score, exploitation requires high privileges and local access, narrowing realistic abuse to attackers who already have admin on the host or to supply-chain/insider scenarios.
Clipboard hijacking in Lenovo's built-in Android browser application allows a malicious website to silently overwrite system clipboard contents on affected devices.

We need to generate a JSON object for CVE-2026-1636. All fields must be plain text strings. Use all provided data: EPSS, KEV not mentioned (so not in KEV), tags, CPE, CVSS 4.0 vector, SSVC, etc. First, understand the vulnerability: "potential DLL hijacking vulnerability was reported in Lenovo Service Bridge that, under certain conditions, could allow a local authenticated user to execute code with elevated privileges." CWE-427: Uncontrolled Search Path Element (DLL hijacking). CVSS 4.0: AV:L/AC:L/AT:P/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N. That is local, low attack complexity, Attack Requirements: P (present? AT:P means attack requirements present, maybe specific conditions), Privileges Required: Low, User Interaction: Passive (UI:P means limited user interaction, e.g., user must open a file or perform some action). Impact: High on vulnerable system confidentiality, integrity, availability; no impact on subsequent system. This matches the description: local authenticated user, elevated privileges. The vector indicates PR:L, so authenticated. AT:P suggests there are some attack requirements beyond just running code, like needing to place a DLL in a specific path or something. EPSS 0.01%, percentile 2%, very low exploitation probability. SSVC: exploitation: none, automatable: no, technical impact: total. So not currently exploited, not automatable, total impact if exploited. Patch available, affected versions: Service Bridge 0 <5.0.2.20 (from EUVD). So fix version is 5.0.2.20 or later. Reference: Lenovo advisory LEN-211071. So we have exact patch. Now, fields: product_name: "Lenovo Service Bridge" (3 words) summary: Synthesize a 2-3 sentence plain-language summary, not copying description. Start with impact verb and product.
