CVE-2026-23144
In the Linux kernel, the following vulnerability has been resolved: mm/damon/sysfs: cleanup attrs subdirs on context dir setup failure When a context DAMON sysfs directory setup is failed after setup of attrs/ directory, subdirectories of attrs/…
Does this matter?
Lower severity and a low EPSS score (0.12%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: mm/damon/sysfs: cleanup attrs subdirs on context dir setup failure When a context DAMON sysfs directory setup is failed after setup of attrs/ directory, subdirectories of attrs/ 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.
