Linux Kernel up to 7.2-rc1 afs afs_insert_volume_into_cell operation after expiration

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to 7.2-rc1. This affects the function afs_insert_volume_into_cell of the component afs. The manipulation with an unknown input leads to a operation after expiration vulnerability. CWE is classifying the issue as CWE-672. The product uses, accesses, or otherwise operates on a resource after that resource has been expired, released, or revoked. This is going to have an impact on integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: afs: Fix the volume AFS_VOLUME_RM_TREE is set on Fix afs_insert_volume_into_cell() to set AFS_VOLUME_RM_TREE on the volume replaced, not the new volume, as it's now removed from the cell's volume tree. This will cause the old volume to be removed from the tree twice and the new volume never to be removed.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2026-72371 since 08/09/2026. The exploitability is told to be easy.
