# CVE-2026-23142

> 3.1 LOW

## Beschreibung

In the Linux kernel, the following vulnerability has been resolved:

mm/damon/sysfs-scheme: cleanup access_pattern subdirs on scheme dir setup failure

When a DAMOS-scheme DAMON sysfs directory setup fails after setup of
access_pattern/ directory, subdirectories of access_pattern/ directory are
not cleaned up.  As a result, DAMON sysfs interface is nearly broken until
the system reboots, and the memory for the unremoved directory is leaked.

Cleanup the directories under such failures.

## Patch verfügbar (OSV)

- Kernel ≥ 6.1.162
- Kernel ≥ 6.6.122
- Kernel ≥ 6.12.67
- Kernel ≥ 6.18.7
