AI-suggested
A fix has been implemented in the Linux kernel media driver for the affected versions. Users should update to patched versions of the linux-hwe-edge kernel that address this issue. Since this is not a cloud service, remediation requires applying the official kernel updates. Patch status is confirmed by the resolved vulnerability report.
Description
A vulnerability in the Linux kernel's media subsystem for Verisilicon Rockchip VPU981 AV1 decoding was resolved. The flaw involved a division by zero risk and potential buffer overflow when processing tile information from the bitstream. The issue was fixed by guarding the division operation and limiting writes to the tile_info DMA buffer. This vulnerability affects specific linux-hwe-edge kernel versions and has a CVSS score of 7.8, indicating a high impact on confidentiality, integrity, and availability.
