Denial of Service

Denial of service in rust-rpm-sequoia allows local attackers to crash RPM signature verification by submitting specially crafted RPM files that trigger unhandled errors in OpenPGP parsing, preventing legitimate package management operations. CVSS 4.0 (low severity), local attack vector, non-authenticating. No public exploit code or active exploitation confirmed.

Denial of Service in vLLM OpenAI-compatible API server allows unauthenticated remote attackers to crash the service via a single HTTP request containing an extremely large n parameter. The lack of upper bound validation causes the asyncio event loop to freeze while allocating millions of request object copies, leading to rapid Out-Of-Memory crashes. CVSS 6.5 with moderate real-world risk due to authentication requirement in the disclosed CVSS vector (PR:L), though the description indicates unauthenticated exploitability - a significant discrepancy warranting clarification from the vendor.

Null pointer dereference in Linux kernel mac80211 IEEE 802.11 wireless subsystem crashes AP_VLAN stations during channel bandwidth change operations. The ieee80211_chan_bw_change() function incorrectly accesses link data on VLAN interfaces (such as 4-address WDS clients) where the link structure is uninitialized, leading to kernel panic when dereferencing a NULL channel pointer. Any system with AP_VLAN wireless configurations and active channel state announcement (CSA) operations is vulnerable to local denial of service.

NULL-pointer dereference in Linux kernel SPI subsystem allows local denial of service via sysfs attribute access. The SPI controller's per-CPU statistics structure is not allocated until after the controller registers with the driver core, creating a race window where sysfs attribute reads can trigger a kernel panic. This affects all Linux kernel versions with the vulnerable SPI statistics implementation; exploitation requires local system access to read sysfs files.

Linux kernel io_uring/poll multishot recv can hang indefinitely when a socket shutdown occurs concurrently with data reception, due to a race condition where accumulated poll wakeups are drained without consuming the persistent HUP event. The vulnerability affects all Linux kernel versions with io_uring poll support and requires a fix to explicitly check for HUP conditions and re-loop when multiple poll activations are pending.

Infinite loop in Linux kernel serial core driver handle_tx() affects systems using uninitialized PORT_UNKNOWN serial ports, where uart_write_room() and uart_write() behave inconsistently regarding null transmit buffers, causing denial of service through system hangs. The vulnerability impacts caif_serial and other drivers that rely on tty_write_room() to determine write capacity. Patch available in upstream kernel commits; no CVSS score assigned due to kernel-specific nature and relatively limited exposure scope.

Linux kernel drm/imagination driver crashes when the GPU runtime PM suspend callback executes concurrently with an IRQ handler attempting to access GPU registers, causing kernel panics with SError interrupts on ARM64 platforms. The vulnerability affects the imagination GPU driver across Linux kernel versions and is triggered when power management suspend operations race with interrupt handling without proper synchronization. The fix adds synchronize_irq() calls to ensure IRQ handlers complete before GPU suspension and removes problematic runtime PM resume calls from the IRQ handler that could cause deadlocks.

Denial of service in Linux kernel amdgpu driver allows local attackers to exhaust system memory by passing an arbitrarily large BO (buffer object) list entry count via userspace, bypassing existing overflow checks but causing excessive allocation and processing delays; fixed by enforcing a 128k entry limit per BO list.

NULL pointer dereference in Linux kernel DRM i915 GPU driver allows local denial of service during system probe when DMC firmware initialization has not yet completed but hardware has DC6 power state enabled. The vulnerability occurs in intel_dmc_update_dc6_allowed_count() when called from gen9_set_dc_state() during intel_power_domains_init_hw(), which executes before DMC initialization, causing kernel oops if DC6 is unexpectedly enabled by BIOS firmware. No public exploit code identified; this is a kernel crash vulnerability requiring local system access triggered by atypical BIOS behavior.

NULL pointer dereference in Linux kernel ROSE socket implementation allows local denial of service when rose_connect() is called twice during an active connection attempt. The vulnerability occurs because rose_connect() fails to validate TCP_SYN_SENT state, permitting rose->neighbour to be overwritten with NULL, which later causes a kernel crash when rose_transmit_link() dereferences the NULL pointer during socket closure. No active exploitation reported; fix available in upstream kernel commits.

Use-after-free vulnerability in Linux kernel ACPI processor errata handling allows local attackers to cause denial of service or potentially execute code via device pointer dereference after reference dropping in acpi_processor_errata_piix4(). The vulnerability affects multiple Linux kernel versions and was introduced in a previous fix attempt (commit f132e089fe89); it has been resolved across stable kernel branches with no active public exploitation identified.

NULL pointer dereference in Linux kernel IPv6 SRv6 path processing allows local denial of service when __in6_dev_get() returns NULL due to missing IPv6 configuration or device unregistration. The vulnerability affects seg6_hmac_validate_skb() and ipv6_srh_rcv() functions which lacked NULL checks on the returned idev pointer, enabling a local attacker to crash the kernel by triggering these code paths on misconfigured or unregistering network devices.

Linux kernel NULL pointer dereference in UDP tunnel socket creation when IPv6 is disabled causes denial of service. When CONFIG_IPV6=n, the udp_sock_create6() function incorrectly returns success (0) without creating a socket, leading callers such as fou_create() to dereference an uninitialized pointer. The vulnerability is triggered via netlink socket operations and requires privileged user access; no public exploit code or active exploitation has been identified at time of analysis.

Denial of service in Linux kernel mvpp2 network driver occurs when MTU changes or other operations trigger buffer pool switching on Marvell hardware lacking CM3 SRAM support, causing NULL pointer dereference in flow control register access. Affects systems running vulnerable kernel versions on Marvell Armada platforms where the CM3 SRAM device tree entry is absent; no authentication required. Upstream fix available via stable kernel commits.

Linux kernel NULL pointer dereference in the x86 PMU NMI handler on AMD EPYC systems causes denial of service when perf event unthrottling races with PMU rescheduling. The vulnerability stems from commit 7e772a93eb61 moving event pointer initialization later in x86_pmu_enable(), allowing the unthrottle path to set active_mask bits without populating the corresponding events[] array entries, leading to NULL pointer dereference when subsequent PMC overflow interrupts fire. No public exploit code identified at time of analysis; patch fixes are available in upstream Linux kernel stable branches.

Null pointer dereference in Linux kernel arm_mpam memory bandwidth monitoring causes kernel oops when an MSC supporting bandwidth monitoring transitions offline and back online. The mpam_restore_mbwu_state() function fails to initialize a value buffer before passing it to __ris_msmon_read() via IPI, triggering a crash in the bandwidth counter restoration routine. This affects ARM systems with MPAM (Memory Partitioning and Monitoring) support and results in denial of service through system instability when memory controllers are toggled.

Linux kernel crashes in iommu_sva_unbind_device() when accessing a freed mm structure after iommu_domain_free() deallocates domain->mm->iommu_mm, causing denial of service on systems using IOMMU Shared Virtual Addressing (SVA). The fix reorders code to access the structure before the domain is freed. No CVSS score, EPSS, or KEV status available; no public exploit code identified.

Unbounded DNS cache in AIOHTTP prior to version 3.13.4 allows remote attackers to cause denial of service through excessive memory consumption. An attacker can trigger repeated DNS lookups with unique hostnames to grow the in-memory cache without bounds, eventually exhausting available system memory. AIOHTTP 3.13.4 and later include a patch that implements cache limits. This is a network-accessible vulnerability requiring no authentication or user interaction, but exploitation requires deliberate attack traffic and does not result in data compromise or system takeover.

Memory exhaustion in aiohttp's header and trailer handling allows remote attackers to cause denial of service by sending attacker-controlled HTTP requests or responses with uncapped header/trailer values. The vulnerability affects aiohttp Python library across affected versions, enabling attackers to exhaust application memory without authentication. A mitigation is available via reverse proxy configuration, and upstream patch has been released.

AppArmor differential encoding verification in the Linux kernel contains logic errors that permit infinite loops to be created through abuse of the verification chain mechanism. Two distinct bugs in the verification routine-conflation of checked states with currently-checked states, and incorrect loop iterator comparison-allow malformed differential encoding chains to bypass security checks. This enables potential information disclosure or policy circumvention on systems relying on AppArmor mandatory access control. The vulnerability affects Linux kernel versions prior to fixes applied across multiple stable branches via kernel commits.

Stack exhaustion in AppArmor profile removal allows local denial of service by crafting deeply nested profiles that trigger recursive kernel stack consumption. The Linux kernel's AppArmor security module can be crashed by a local user with permission to load profiles via the apparmor_parser tool and trigger removal through sysfs, causing kernel stack overflow. The fix replaces recursive profile removal with an iterative approach to prevent stack exhaustion.

The vulnerability stems from a null pointer dereference in message handling logic (CWE-476) and carries a CVSS 6.5 score reflecting high availability impact with low attack complexity. Vendor-released patch available via GitHub release v1.7.0.

Ella Core's AMF control plane deadlocks in the SCTP notification handler when processing malformed or stale radio entries, allowing unauthenticated attackers with N2 interface access to hang the entire Access and Mobility Function until manual process restart, completely denying service to all subscribers. The vulnerability (CVSS 6.5, CWE-833 deadlock) stems from improper synchronization in radio cleanup logic combined with stale-entry scanning, and patches are available in version 1.7.0 and later.

Ella Core suffers a null pointer dereference vulnerability in its NGAP LocationReport message handler that causes the process to panic and crash, enabling unauthenticated network-adjacent attackers to trigger denial of service affecting all connected mobile subscribers. The vulnerability (CVE-2026-33903, CVSS 6.5) stems from missing input validation guards and has a vendor-released patch available in version 1.7.0; no public exploit code or active exploitation has been identified at time of analysis.

TSPortal versions prior to 34 contain an uncontrolled resource creation vulnerability that allows authenticated attackers to generate arbitrary user database records through validation logic abuse, resulting in potential denial of service via uncontrolled database growth. The flaw exists in Miraheze's Trust and Safety management platform (cpe:2.3:a:miraheze:tsportal) and requires low-privilege authenticated access to exploit. Vendor-released patch available in version 34; no public exploit identified at time of analysis.

libssh attempts to open arbitrary files during configuration parsing, allowing local attackers with limited privileges to trigger a denial of service by forcing access to dangerous files such as block devices or large system files. The vulnerability affects Red Hat Enterprise Linux versions 6, 7, 8, 9, and 10, as well as Red Hat OpenShift Container Platform 4, and requires local access with low privileges to exploit. No public exploit code or active exploitation has been confirmed at the time of analysis.
