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: libceph: fix potential use-after-free in have_mon_and_osd_map()

A use-after-free vulnerability was found in the Ceph client session initialization in the Linux kernel. The havemonandosdmap function checks map epochs without holding the appropriate locks, racing with concurrent map updates that free the old map. This can result in dereferencing freed memory...
