afs: Fix the volume AFS_VOLUME_RM_TREE is set on
Overview
Description
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.

Scoring
CVSS Scores
The Common Vulnerability Scoring System is a standardized framework
for assessing the severity of vulnerabilities in software and systems.
We collect and displays CVSS scores from various sources for each CVE.
| Score | Version | Severity | Vector | Exploitability Score | Impact Score | Source |
|---|---|---|---|---|---|---|
| CVSS 3.1 | HIGH | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 |
Solution
Apply kernel updates to fix volume removal logic and prevent double removal.
- Update the Linux kernel to the patched version.
- Verify the AFS volume removal logic is corrected.
- Ensure old volumes are removed correctly.
- Ensure new volumes are not removed.
