Kernel: race condition leads to use after free during vma lock in lock_vma_under_rcu
A use-after-free flaw was found in the Linux kernel's Memory Management subsystem when a user wins two races at the same time with a fail in the mas_prev_slot function. This issue could allow a local user to crash the system.
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
