Lifecycle Timeline
3Description
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.
Analysis
Linux kernel DAMON sysfs interface fails to properly clean up access_pattern subdirectories when scheme directory setup fails, causing memory leaks and rendering the sysfs interface non-functional until system reboot. A local privileged user can trigger this condition to degrade system functionality and exhaust memory resources. …
