CVE-2026-74647

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A race condition exists in the fastrpc req munmap impl() function. The issue occurs because buffers are removed from the list only after they are unmapped from the DSP. When multiple threads invoke the unmap operation concurrently, one thread might remove an entry from the list while another thread is still performing an unmap operation on that same entry.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
