Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

CVE-2026-53391 (opens in a new tab)How to fix?

Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference in the nfs4_decode_mp_ds_addr process. An attacker can cause a kernel panic and deny service by sending a crafted GETDEVICEINFO response with a zero-length r_addr field from a malicious or compromised NFS metadata server. This is only exploitable if the system is configured as a pNFS-flexfile client mounted against such a server.
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
