CVE-2022-49165

Kernel crash via mismatched JPEG buffer planes

Published Feb 26, 2025 · Updated May 11, 2026

NULL pointer dereference in the Linux kernel's i.MX JPEG driver allows local users to crash the system via mismatched buffers. The decode path accepts an NV12M JPEG output buffer with a single-planar capture buffer, and mxc_jpeg_addrs then requests an absent second plane. A low-privilege local process must access an i.MX JPEG device and queue that format mismatch; successful triggering causes a kernel crash only.
