CVE-2026-23288
Description
A flaw was found in the Linux kernel's accel/amdxdna component. This vulnerability occurs when clearing a command header with memset() before verifying the available slot space, which can be smaller than the header size. This can lead to an out-of-bounds write and memory corruption. An attacker could potentially exploit this to cause a denial of service or other unpredictable system behavior.
Understanding the Weakness (CWE)
Integrity,Availability,Confidentiality
Technical Impact: DoS: Crash, Exit, or Restart; Execute Unauthorized Code or Commands; Read Memory; Modify Memory
If the incorrect calculation is used in the context of memory allocation, then the software may create a buffer that is smaller or larger than expected. If the allocated buffer is smaller than expected, this could lead to an out-of-bounds read or write (CWE-119), possibly causing a crash, allowing arbitrary code execution, or exposing sensitive data.
