CVE-2026-43222
Description
A flaw was found in the Linux kernel's media: verisilicon: AV1 driver. The driver incorrectly calculates the buffer size for tile information, which can lead to writing data beyond the allocated memory. This memory corruption vulnerability could result in system instability or a denial of service.
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.
