CVE-2023-52935

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

Description A race condition exists in the Linux kernel related to the ->anon vma attachment to the VMA. The issue arises when collapse and free pmd() requires the ->anon vma to be locked, but the lock is not properly held, allowing for concurrent page table access. This can lead to use-after-free access and lockdep warnings. The vulnerability is related to page table traversal and removal, which requires holding the mmap lock, the anon vma lock, and the mapping lock.

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