AI-suggested
A fix has been implemented in the Linux kernel to add a timeout during stop_streaming in the chips-media wave5 driver. Users should update to a patched kernel version to remediate this issue. Specific patch links are not provided, so users should consult their Linux distribution vendor for updated kernel packages.
Description
A vulnerability in the Linux kernel's media chips-media wave5 driver could cause an infinite loop when stop_streaming is called. This occurs because the code lacks a timeout while waiting for queues to drain. The issue has been resolved by adding a bounded poll with a timeout to prevent indefinite looping.
