Overview

Affected versions of this package are vulnerable to Buffer Overflow in the perf_event_overflow process. An attacker can cause memory corruption or system instability by triggering removal of entries from sched_cb_list while the list node is still in use, such as by invoking ioctl with PERF_EVENT_IOC_REFRESH when the event limit reaches zero.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
