CVE-2023-5717 (GCVE-0-2023-5717)

Vulnerability from cvelistv5 – Published: 2023-10-25 12:55 – Updated: 2026-02-25 17:20

Title

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

Summary

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.
