CVE-2024-54683

CVE-2024-54683 – Linux kernel netfilter IDLETIMER ABBA deadlock : The vulnerability occurs when deleting the last idletimer rule may race with a read of its sysfs file, risking a circular locking dependency between idletimer teardown and kernel lock ownership. A reproduction shows concurrent dele...

CVE-2024-54191

CVE-2024-54191 affects the Linux kernel Bluetooth stack (ISO). The issue arises from a circular lock between the socket lock and hdev lock in the ISO path. The fix reworks iso_sock_recvmsg and related code so that the socket lock is released before acquiring hdev, breaking the circular dependency...

CVE-2024-53689

CVE-2024-53689 pertains to the Linux kernel and describes a deadlock risk in the queue handling path. The root cause is an incorrect ordering in the block: the code freezes the queue (via q_usage_counter) before acquiring sysfs_lock, whereas the typical safe order is to acquire sysfs_lock prior t...
