kernel: ext4: fix use-after-free in ext4_orphan_cleanup

A use-after-free vulnerability was found in the ext4 filesystem's orphan inode cleanup routine in the Linux kernel. When ext4inodeattachjinode fails with -ENOMEM during orphan cleanup at mount time, the error is not properly propagated. The inode is freed via iput, but the orphan list still...

kernel: net/mlx5e: fix memory leak in mlx5e_ptp_open

A flaw was found in the Linux kernel net/mlx5e Ethernet driver’s mlx5eptpopen function. When memory allocation via kvzallocnode or kvzalloc fails, previously allocated resources c or cparams were not properly freed, leading to a memory leak in the error path. An unprivileged local user interactin...
