CVE-2026-45848

Опубликовано: 27 мая 2026

Описание

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix NULL sock in aa_sock_file_perm Deal with the potential that sock and sock-sk can be NULL during socket setup or teardown. This could lead to an oops. The fix for NULL pointer dereference in __unix_needs_revalidation shows this is at least possible for af_unix sockets. While the fix for af_unix sockets applies for newer mediation this is still the fall back path for older af_unix mediation and other sockets, so ensure it is covered.

A flaw was found in the Linux kernel's AppArmor security module. This vulnerability allows a local attacker to trigger a NULL pointer dereference during socket setup or teardown operations. This can lead to a kernel 'oops', resulting in a system crash and a Denial of Service (DoS).
