kernel: use-after-free related to leaf anon_vma double reuse

A memory leak flaw with use-after-free capability was found in the Linux kernel. The VMA mm/rmap.c functionality in the ismergeableanonvma function continuously forks, using memory operations to trigger an incorrect reuse of leaf anonvma. This issue allows a local attacker to crash the system...

The vulnerability of the Linux operating system’s DVB driver allows a hacker to cause a service failure or gain increased privileges.

The vulnerability of the Linux operating system’s DVB kernel driver is related to the use of previously freed memory in the drivers/media/dvb-core/dvbcaen50221.c file when the device is closed, provided that it was turned off beforehand. Exploiting this vulnerability can allow an attacker to caus...

CVE-2021-23134 Linux kernel llcp_sock_bind/connect use-after-free

Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAPNETRAW capability...

There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed it can cause an exploitable condition as the process wakes up to terminate and clean all attached files. The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the inode.
