CVE-2026-43222 Details
Description
In the Linux kernel, the following vulnerability has been resolved: media: verisilicon: AV1: Fix tile info buffer size Each tile info is composed of: row_sb, col_sb, start_pos and end_pos (4 bytes each). So the total required memory is AV1_MAX_TILES * 16 bytes. Use the correct #define to allocate the buffer and avoid writing tile info in non-allocated memory.
A vulnerability in the Linux kernel's handling of tile information for the Verisilicon AV1 decoder can lead to a buffer overflow. Each tile's information requires a specific amount of memory, and the vulnerability arises from incorrect memory allocation, allowing tile data to be written into unallocated memory. This issue affects the stable version of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel, where this vulnerability has been addressed. Instructions for downloading the patched version are available on the official Linux kernel website.
