Description
A flaw was found in the Linux kernel's media subsystem, specifically within the wave5 encoder. A local user could exploit a race condition during encoder processing, where a buffer is returned to userspace before being fully removed from the ready queue. This could lead to a corrupted buffer list, potentially causing a system crash and resulting in a denial of service.
Statement
This issue affects Chips&Media wave5 video encoder. src_buf removed too early relative to IRQ buffer return race. Systems without wave5 encoder are not affected.
