CVE-2022-49163

Kernel panic via unchecked JPEG slot index

Published Feb 26, 2025 · Updated Aug 5, 2026

Out-of-bounds access in the imx-jpeg driver in affected Linux kernel releases allows local users to trigger a kernel panic. When JPEG parsing fails before a hardware slot is acquired, the driver retains MXC_MAX_SLOTS and indexes past slot_data, overwriting the adjacent num_domains field. Access to the i.MX JPEG video device and a module unload-and-reload sequence are required; the corrupted domain count prevents power-domain detachment and panics the host during the next module load.
