Description
A flaw was found in the Linux kernel. A local user can exploit this vulnerability by setting the `nr_contexts` parameter to zero via the DAMON sysfs interface while DAMON (Data Access MONitor) is active. This improper input validation leads to a NULL pointer dereference, which can cause a system crash and result in a Denial of Service (DoS).
