CVE-2022-50668

CVE-2022-50668 refers to a Linux kernel/ext4 issue where deadlock can occur when manipulating xattr blocks in mbcache. The root cause is a non-atomic update of the e_reusable bit within a bitfield, which can race with updates to e_referenced, creating an inconsistent state that the function ext4_...

CVE-2023-53809

The CVE-2023-53809 issue affects the Linux kernel where passing a pppol2tp socket as a UDP socket to l2tp_tunnel_register() could trigger a recursive locking deadlock. Root cause: a lock order condition allowed deadlock when a socket path led to nested locking of sk_lock-AF_PPPOX. The advisory no...
