CVE-2026-49421
The kernel function that implements unlinkat2 and funlinkat2 validated the ATRESOLVEBENEATH flag but failed to pass it through to the underlying path lookup. The flag was silently dropped, so path resolution was not actually restricted. A process that uses ATRESOLVEBENEATH with unlinkat2 or...
CVE-2026-49421
The FreeBSD kernel is vulnerable in the unlinkat(2) and funlinkat(2) system calls because they validate the AT_RESOLVE_BENEATH flag but fail to pass it to the underlying path lookup. Because this flag is silently dropped, path resolution is not restricted, allowing a process to resolve paths abov...
