AI-suggested
A fix has been implemented in the Linux kernel to properly free the scan_mask on buffer release. Users should update to a patched kernel version that includes this fix to mitigate the issue.
Description
A memory management vulnerability in the Linux kernel's Industrial I/O (iio) subsystem was fixed by ensuring the scan_mask bitmap is properly freed on buffer release. The flaw originated from a code change that moved scan_mask to a separate allocation but did not update the release function accordingly, potentially causing a memory leak.
