CVE-2026-64438

A flaw was found in the Linux kernel's crypto QAT QuickAssist Technology module. A race condition exists during the teardown of Virtual Function to Physical Function VF2PF work in the adfdisablesriov function. This allows a concurrently scheduled or already queued worker to attempt to access memo...

CVE-2026-64305

A flaw was found in the Linux kernel's cryptographic acceleration qat component. This vulnerability occurs because certain functions iterate over a critical data structure without proper synchronization. If another operation modifies this structure concurrently, it can lead to data corruption or ...

USN-8595-3 linux-aws-6.8, linux-aws-fips vulnerabilities

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix mm struct reference leak in aie2 populate range aie2 populate range jumps back to the again label without calling mmputmm, leaking a reference to the mm struct. Add the missing mmput before jumping to again...

CVE-2026-55999

A flaw was found in the glamorfontget function of the xorg-x11-server. This vulnerability, a heap buffer overflow, occurs when the server processes a specially crafted PCF font file where individual glyph metrics exceed the declared maximum bounds. An authenticated X client can exploit this by...

CVE-2026-40257

CVE-2026-40257 affects OP-TEE (Trusted Execution Environment) for Cortex-A with TrustZone. From versions 3.21.0 up to, but not including, 4.11.0, the ARM Crypto Extensions accelerated SHA-3 implementation has an off-by-one error that can cause a massive heap overflow, corrupting all TEE kernel me...

CVE-2026-40257 OP-TEE has SHA-3 accelerated finalize heap overflow

OP-TEE is a Trusted Execution Environment TEE designed as companion to a non-secure Linux kernel running on Arm; Cortex-A cores using the TrustZone technology.
