CVE-2026-72373 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 6.12.97, 6.18.40, 7.1.5 or higher.
Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference in the afs_break_some_callbacks process due to a missing NULL pointer check after calling afs_lookup_volume_rcu. An attacker can cause a kernel crash and deny system availability by sending a crafted callback notification from a malicious or compromised AFS fileserver, which triggers a NULL pointer dereference in the kernel's AFS client callback path.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
