Linux kernel device driver Heap Buffer Overflow DoS

The vulnerability of the classregister function in the drivers/base/class.c file of the Linux kernel’s device driver framework is related to the repeated release of previously released memory. Exploiting this vulnerability could allow an attacker to cause a system failure...

Linux kernel device driver Class Register Code Execution

The vulnerability of the classregister function in the Linux kernel device driver framework is related to the use of memory after it is freed. Exploiting this vulnerability can allow an attacker to execute arbitrary code...

CVE-2023-52468

The CVE-2023-52468 entry describes a Linux kernel use-after-free in class_register. The issue arises because lock_class_key remains registered in lock_keys_hash after subsys_private is freed in an error path, so a task iterating the hash later may trigger a use-after-free. The fix unregisters the...
