| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.6.61
Description:
A memory leak issue has been identified in the Linux kernel, specifically in the iio gts build avail scale table() function. This issue occurs when the per time gains[i] is not freed, which is allocated in the "gts->num itime" for loop. The memory leak is triggered by modprobe iio-test-gts and rmmod, resulting in unreferenced objects. The issue includes multiple instances of "size 64" and "size 16" memory leaks, corresponding to specific function calls.
Recommendations:
To resolve the issue, update to Linux kernel version 6.6.61 or later. As a temporary workaround, consider disabling the iio-test-gts module until a patch is available. Restrict access to the vulnerable iio gts build avail scale table() function to minimize the risk of exploitation. Avoid using the per time gains[i] variable in the affected function until the issue is resolved.
