Overview

Affected versions of this package are vulnerable to Out-of-Bounds Write in the 'perf' component. An attacker can achieve local privilege escalation.

Note:

This occurs when perf_read_group() is called while an event's sibling_list is smaller than its child's sibling_list, leading to incrementing or writing to memory locations outside of the allocated buffer.
