kernel: ext4: fix invalid free tracking in ext4_xattr_move_to_block()

A memory management flaw was found in the Linux kernel's ext4 filesystem extended attribute handling. In ext4xattrmovetoblock, when moving an extended attribute value to an external block, the code checks entry-evalueinum to determine if the buffer was allocated via kvmalloc. However, at cleanup...

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...
