CVE-2024-57886 |
Description: In the Linux kernel, the following vulnerability has been resolved:
mm/damon/core: fix new damon_target objects leaks on damon_commit_targets()
Patch series "mm/damon/core: fix memory leaks and ignored inputs from
damon_commit_ctx()".
Due to two bugs in damon_commit_targets() and damon_commit_schemes(),
which are called from damon_commit_ctx(), some user inputs can be ignored,
and some mmeory objects can be leaked. Fix those.
Note that only DAMON sysfs interface users are affected. Other DAMON core
API user modules that more focused more on simple and dedicated production
usages, including DAMON_RECLAIM and DAMON_LRU_SORT are not using the buggy
function in the way, so not affected.
This patch (of 2):
When new DAMON targets are added via damon_commit_targets(), the newly
created targets are not deallocated when updating the internal data
(damon_commit_target()) is failed. Worse yet, even if the setup is
successfully done, the new target is not linked to the context. Hence,
the new targets are always leaked regardless of the internal data setup
failure. Fix the leaks.

CVE-2024-57883 |
Description: In the Linux kernel, the following vulnerability has been resolved:
mm: hugetlb: independent PMD page table shared count
The folio refcount may be increased unexpectly through try_get_folio() by
caller such as split_huge_pages. In huge_pmd_unshare(), we use refcount
to check whether a pmd page table is shared. The check is incorrect if
the refcount is increased by the above caller, and this can cause the page
table leaked:

CVE-2024-57801 |
Description: In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Skip restore TC rules for vport rep without loaded flag
During driver unload, unregister_netdev is called after unloading
vport rep. So, the mlx5e_rep_priv is already freed while trying to get
rpriv->netdev, or walk rpriv->tc_ht, which results in use-after-free.
So add the checking to make sure access the data of vport rep which is
still loaded.
