Pending analysis
Type:
CWE-476
NULL Pointer Dereference
Publication date:

Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
mm/damon/lru_sort: handle ctx allocation failure<br />
<br />
DAMON_LRU_SORT allocates the damon_ctx object for its kdamond in its init<br />
function. damon_lru_sort_enabled_store() wrongly assumes the allocation<br />
will always succeed once tried. If the damon_ctx allocation was failed,<br />
therefore, code execution reaches to damon_commit_ctx() while &#39;ctx&#39; is<br />
NULL. As a result, it dereferences the NULL &#39;ctx&#39; pointer. Avoid the<br />
NULL dereference by returning -ENOMEM if &#39;ctx&#39; is NULL.
