AI-suggested
A patch is available that fixes the race condition by acquiring the necessary mutex before executing commands. Users should apply the official Linux kernel updates that address this vulnerability. No additional mitigation steps are indicated by the vendor advisory.
Description
A race condition vulnerability in the Linux kernel's ims-pcu driver was fixed. The ims_pcu_reset_device() sysfs callback did not acquire the necessary mutex before calling ims_pcu_execute_command(), which could lead to data races and corruption of the shared command buffer if commands were triggered concurrently. This flaw has been addressed by acquiring the mutex before executing commands. The vulnerability affects specific Linux kernel versions and has a low severity rating. A patch is available to resolve this issue.
