Description

A flaw was found in the Linux kernel's DAMON (Data Access MONitor) sysfs (system file system) component. This vulnerability, a use-after-free, occurs because the damon_sysfs_quot_goal->path buffer can be deallocated during a write operation without proper locking. A local user could exploit this race condition by reading the 'path' file while it is being deallocated, potentially leading to information disclosure or a denial of service.
