Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel related to a race condition involving Virtual Memory Area (VMA) iteration and the teardown of the mm struct. Specifically, the issue occurs during the exit mmap() process, where VMAs and the maple tree are torn down while holding the mmap lock in write mode. This can lead to dereferencing a destroyed maple tree, potentially causing a lock dependency warning. The fix involves checking ksm test exit() after acquiring the mmap lock in read mode, and skipping the for each vma() iterator if the maple tree has been destroyed.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
