Lock Management Issue in Linux Kernel Affects Media Chips

CVE-2026-97514

What is CVE-2026-97514?

A vulnerability in the Linux kernel related to the handling of dynamic resolution in media chips has been resolved. The issue arose from improper lock management within the handle_dynamic_resolution_change function. Specifically, the function did not acquire the necessary state lock before execution, which could result in potential sleep calls within the locked state. This potentially exposes the system to concurrency issues. The fix ensures that the fbc_buf_count is stored and updated properly only after releasing the lock, preventing lock contention and enhancing overall stability.
