Vulnerability from github – Published: 2023-12-19 15:30 – Updated: 2025-02-13 18:32

Details

A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation.

A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group().

We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b.

Severity ?

7.8 (High)
