Astra Linux – Vulnerability in Linux 5.15

A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to gain local privilege escalation. The perfgroupdetach function did not check the attachstate of the event’s siblings before calling addeventtogroups; moreover, removeonexec allowed calling listdelevent...

The vulnerability of the perf_group_detach() function in the Linux operating system’s kernel utilities allows attackers to increase their privileges.

The vulnerability of the perfgroupdetach function in the Linux operating system’s kernel perf utility stems from the use of memory after it is freed, especially when dealing with event handling. Exploiting this vulnerability can allow an attacker to gain increased privileges...
