Linux 6.6 Race Condition Exploit

A security-relevant race between mremap and THP code has been discovered. Reaching the buggy code typically requires the ability to create unprivileged namespaces. The bug leads to installing physical address 0 as a page table, which is likely exploitable in several ways: For example, triggering...
