CVE-2026-53335

Description

In the Linux kernel, the following vulnerability has been resolved: mm/damon/lru_sort: handle ctx allocation failure DAMON_LRU_SORT allocates the damon_ctx object for its kdamond in its init function. damon_lru_sort_enabled_store() wrongly assumes the allocation will always succeed once tried. If the damon_ctx allocation was failed, therefore, code execution reaches to damon_commit_ctx() while -ctx- is NULL. As a result, it dereferences the NULL -ctx- pointer. Avoid the NULL dereference by returning -ENOMEM if -ctx- is NULL.
