CVE-2026-43463

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the rxrpc and afs components where the rxrpc kernel lookup peer() function can return error pointers in addition to NULL. The system failed to properly check for these error pointers, as it only verified if the return value was NULL.

Recommendations Update the Linux kernel to a version where rxrpc kernel lookup peer() returns -ENOMEM on allocation failure and callers in afs utilize IS ERR() and PTR ERR() to handle the returned error codes.
