A Qualcomm chipset vulnerability (CVE-2026-21385) causes memory corruption through improper integer handling during memory allocation, enabling local privilege escalation to kernel level. KEV-listed and patched, this vulnerability affects Qualcomm-based mobile devices and embedded systems, potentially impacting billions of Android devices globally.
Memory Corruption when adding user-supplied data without checking available buffer space. [CVSS 7.8 HIGH]
Memory Corruption when accessing trusted execution environment without proper privilege check. [CVSS 7.8 HIGH]
Memory Corruption when accessing a buffer after it has been freed while processing IOCTL calls. [CVSS 7.8 HIGH]
Memory Corruption when accessing buffers with invalid length during TA invocation. [CVSS 7.8 HIGH]
Memory Corruption while deallocating graphics processing unit memory buffers due to improper handling of memory pointers. [CVSS 7.8 HIGH]
Memory Corruption when initiating GPU memory mapping using scatter-gather lists due to unchecked IOMMU mapping errors. [CVSS 7.8 HIGH]
Cryptographic issue when a Trusted Zone with outdated code is triggered by a HLOS providing incorrect input. [CVSS 7.1 HIGH]
Memory corruption occurs when a secure application is launched on a device with insufficient memory. [CVSS 7.8 HIGH]
Memory corruption when copying overlapping buffers during memory operations due to incorrect offset calculations. [CVSS 7.8 HIGH]
Memory corruption while passing pages to DSP with an unaligned starting address. [CVSS 7.8 HIGH]
Information disclosure when a weak hashed value is returned to userland code in response to a IOCTL call to obtain a session ID. [CVSS 5.5 MEDIUM]
Memory corruption while processing identity credential operations in the trusted application. [CVSS 7.8 HIGH]
Memory corruption while processing a secure logging command in the trusted application. [CVSS 7.8 HIGH]
Cryptographic issue may occur while encrypting license data. [CVSS 8.4 HIGH]
Memory corruption while handling sensor utility operations. [CVSS 6.7 MEDIUM]
Memory corruption while deinitializing a HDCP session. [CVSS 7.8 HIGH]
Memory corruption while accessing a synchronization object during concurrent operations. [CVSS 6.7 MEDIUM]
Memory corruption while processing shared command buffer packet between camera userspace and kernel. [CVSS 6.7 MEDIUM]
Memory corruption while handling buffer mapping operations in the cryptographic driver. [CVSS 6.6 MEDIUM]
Memory corruption while processing a config call from userspace. [CVSS 6.7 MEDIUM]
Information disclosure while processing a firmware event. [CVSS 6.1 MEDIUM]
Transient DOS while parsing video packets received from the video firmware. [CVSS 5.5 MEDIUM]
Transient DOS when a remote device sends an invalid connection request during BT connectable LE scan. Rated medium severity (CVSS 6.5), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
Local privilege escalation in Qualcomm's DSP service buffer-allocation path affects numerous FastConnect, QMP1000, SM-series, and Snapdragon mobile/wearable platform firmware components. The flaw is a use-after-free (CWE-416) that allows an authenticated local attacker with low privileges-such as a malicious app or compromised unprivileged process able to reach the DSP IPC interface-to corrupt memory and potentially execute code in the DSP context, yielding high confidentiality, integrity, and availability impact. No public exploit identified at time of analysis, and EPSS is 0.09%, so priority is bounded by the local-only attack vector despite the 7.8 CVSS score.
Memory corruption in Qualcomm firmware - an out-of-bounds write (CWE-787) triggered when the reboot code path parses a malformed license file - can lead to code execution or denial of service in the affected subsystem. The flaw is local and privilege-dependent: per the CVSS vector (AV:L/PR:L/UI:N) the attacker must already hold a local foothold with low privileges on the device and must be able to place or influence the license file before a reboot, so it is not a remote or default-unauthenticated condition. No public exploit code has been identified at time of analysis (EPSS is 0.09%, percentile-based score negligible), and there is no confirmed active exploitation.
Memory corruption in Qualcomm's PlayReady Trusted Application (TA) occurs when the TA processes crafted commands, and since the vulnerability is reachable only through the local trusted-execution environment it requires an attacker who can already run code on the device at app privilege level. Successful exploitation could corrupt memory within the Trusted Execution Environment and lead to code execution or integrity loss (CWE-131, Incorrect Calculation of Buffer Size), affecting a very broad range of Qualcomm chipsets across mobile, modem, IoT, automotive, compute, and wearable platforms. No public exploit code has been identified and EPSS is negligible (0.09%, 0th percentile), so this is an access-gated issue that matters most to devices that ship and rely on the affected PlayReady TA.
