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.
