CVE-2023-54311

In the Linux kernel, the following vulnerability has been resolved: ext4: fix deadlock when converting an inline directory in nojournal mode In no journal mode, ext4finishconvertinlinedir can self-deadlock by calling ext4handledirtydirblock when it already has taken the directory lock. There is a...

CVE-2023-54288 wifi: mac80211: fortify the spinlock against deadlock by interrupt

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fortify the spinlock against deadlock by interrupt In the function ieee80211txdequeue there is a particular locking sequence: begin: spinlock&local-queuestopreasonlock; qstopped = local-queuestopreasonsq;...

CVE-2023-54288

The CVE-2023-54288 entry pertains to the Linux kernel’s wifi mac80211 stack. A deadlock risk arises in ieee80211_tx_dequeue() due to a race between spin_lock and spin_unlock around queue_stop_reason_lock when an asynchronous interrupt occurs, potentially re-locking the same spinlock. This can lea...

CVE-2023-54281

CVE-2023-54281 (Linux kernel, btrfs) : The issue affects the btrfs inode lookup path during ino_lookup ioctl. When ino_lookup triggers btrfs_iget() to obtain an inode reference while holding the root btree, it may need to acquire an additional lock on the same/btrfs root path, risking a deadlock ...
