HIGH 7.8

DescriptionCVE.org

In the Linux kernel, the following vulnerability has been resolved:

accel/amdxdna: Prevent ubuf size overflow

The ubuf size calculation may overflow, resulting in an undersized allocation and possible memory corruption.

Use check_add_overflow() helpers to validate the size calculation before allocation.

AnalysisAI

A size calculation overflow vulnerability exists in the Linux kernel's accel/amdxdna driver that can result in undersized buffer allocations and potential memory corruption. The vulnerability affects Linux kernel versions across multiple branches where the AMD XDNA accelerator driver is compiled. An attacker with local access could exploit this to trigger memory corruption, potentially leading to denial of service or privilege escalation, though exploitation complexity and attack surface requirements remain moderate.

Technical ContextAI

The vulnerability resides in the AMD XDNA accelerator (accel/amdxdna) driver within the Linux kernel, which manages hardware acceleration for AMD's XDNA devices. The root cause is an integer overflow in ubuf (user buffer) size calculation that occurs before memory allocation. The affected CPE is cpe:2.3:a:linux:linux:*:*:*:*:*:*:*:*, indicating all Linux kernel versions are potentially affected depending on build configuration. The vulnerability class relates to insufficient input validation during arithmetic operations (CWE-190: Integer Overflow or Wraparound), where unchecked size calculations bypass intended allocation limits. The fix implements check_add_overflow() helper functions to validate arithmetic operations before allocation, preventing malicious or malformed input from causing integer wraparound conditions.

RemediationAI

Apply the latest Linux kernel patch by upgrading to a kernel version that includes the overflow check fix, available in stable branches via https://git.kernel.org/stable/c/1500b31db94374a6669e73ce94d6f71cf8e85e06 and related commits. For distributions, check with your Linux vendor (Red Hat, Canonical, SUSE, etc.) for backported kernel updates addressing CVE-2026-23280. If immediate patching is not feasible, disable or unload the amdxdna driver module using modprobe -r amdxdna if the hardware is not in active use, and restrict access to device ioctl interfaces through SELinux or AppArmor policies. Prioritize patching for systems running AMD XDNA accelerators in production environments or shared compute platforms.
