CVE-2026-99225 Nov 2, 2026 Source: Vendor
In the Linux kernel, the following vulnerability has been resolved:
keys: Check the authorization payload in process keyring searches
An authorization payload and its saved credentials must remain valid
while search_process_keyrings_rcu() searches the requestor's keyrings.
The function validates the authorization key, then separately loads
payload.data[0] and unconditionally reads rka->cred. Validation does
not prevent request_key_auth_revoke() from clearing the payload.
A request-key helper
