CVE-2024-53096Public exploit

Local privilege escalation via stale writable page mappings

Published Nov 25, 2024 · Updated Aug 5, 2026

Use-after-free in affected Linux kernel releases allows local users to read and write kernel memory through a crafted mmap call. mmap_region runs fallible checks after a driver mmap hook succeeds, then closes the VMA while installed page-table entries remain live and writable. An unprivileged process can enable MDWE and map a driver-backed file descriptor to obtain stale kernel-memory access or trigger a kernel panic.
