Description

A flaw was found in the Linux kernel. When updating DAMON (Data Access MONitor) parameters, an internal memory allocation failure during the damon_commit_ctx() function could leave the DAMON context in a partially corrupted state. If this corrupted context is subsequently used, it can lead to unexpected system behaviors, including a NULL pointer dereference. While the real-world impact is considered rare, this vulnerability could potentially cause system instability.
