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 while invoking IOCTL calls when concurrent access to shared buffer occurs. [CVSS 7.8 HIGH]
5G Fixed Wireless Access Platform Firmware versions up to - contains a vulnerability that allows attackers to cryptographic issue when a VoWiFi call is triggered from UE (CVSS 7.2).
Memory Corruption when concurrent access to shared buffer occurs due to improper synchronization between assignment and deallocation of buffer resources. [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 concurrent access to shared buffer occurs during IOCTL calls. [CVSS 7.8 HIGH]
Memory corruption while handling different IOCTL calls from the user-space simultaneously. [CVSS 7.8 HIGH]
Memory Corruption when accessing buffers with invalid length during TA invocation. [CVSS 7.8 HIGH]
5G Fixed Wireless Access Platform Firmware versions up to - is affected by reachable assertion (CVSS 6.5).
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]
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 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]
Memory corruption in Qualcomm firmware's Generic Packet Router (GPR) lets a locally present, low-privileged attacker escalate to root-level code execution on a broad range of Snapdragon, FastConnect, QAM/QCA/QCN and related chipsets. Per the CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, base 7.8), the flaw requires an existing foothold as an unprivileged local process - a malicious or compromised app, for example - which then routes an oversized data packet through the GPR path that bridges user and root/kernel contexts, triggering a CWE-190 integer overflow and full compromise of confidentiality, integrity and availability. It is not remotely reachable, and no public exploit code or confirmed active exploitation was identified at time of analysis; Qualcomm published the issue in its December 2025 security bulletin for OEM distribution.
Memory corruption due to global buffer overflow when a test command uses an invalid payload type. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.
