A use-after-free vulnerability in KVM's shadow paging code that can lead to kernel memory corruption and denial of service (DoS) issues. The vulnerability arises when a shadow page table entry (SPTE) is overwritten without proper cleanup of the reverse mapping (rmap), resulting in dereferencing a stale pointer.
