CVE-2023-5717

Out-of-bounds write in Linux kernel's Linux Kernel Performance Events (perf) component

Published Oct 25, 2023 CVSS 3.1 · 7.8 High EPSS < 1% KEV · Not listed
Description
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.
