Doc Text:
A flaw was found in the Linux kernel's Performance Events system component. A condition can be triggered that allows data to be written past the end or before the beginning of the intended memory buffer. This issue may lead to a system crash, code execution, or local privilege escalation.

Description Avinash Hanwate 2023-10-30 08:44:58 UTC 
A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf) component can be exploited to achieve local privilege escalation.

If perf_read_group() is called while an event's sibling_list is smaller than its child's sibling_list, it can increment or write to memory locations outside of the allocated buffer.

We recommend upgrading past commit 32671e3799ca2e4590773fd0e63aaa4229e50c06.
