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.
A flaw was found in the Linux kernel's Data Access MONitor (DAMON) sysfs interface. A local attacker, typically a privileged user, could exploit a cleanup bug during DAMON context setup. If the setup fails after the attrs directory is created, stale sysfs directories are left behind. This can lead to a local denial of service, making the DAMON sysfs interface unusable until a system reboot, and potentially cause a kernel memory leak if repeatedly triggered.
