Official description

In the Linux kernel, the following vulnerability has been resolved: mm/damon/reclaim: fix potential memory leak in damon_reclaim_init() damon_reclaim_init() allocates a memory chunk for ctx with damon_new_ctx(). When damon_select_ops() fails, ctx is not released, which will lead to a memory leak. We should release the ctx with damon_destroy_ctx() when damon_select_ops() fails to fix the memory leak.
