CVE-2026-99245

In the Linux kernel, the following vulnerability has been resolved:

KEYS: Fix key_reject_and_link() race with keyring restriction

The restrict_link check in key_reject_and_link() is done before taking the keyring semaphore, racing with a concurrent keyring_restrict() that installs the restriction while holding the semaphore in write mode.

Move the check to after __key_link_lock(), so it is done under the semaphore, matching the pattern used in __key_create_or_update().
