Overview
Affected versions of this package are vulnerable to Buffer Overflow in the ring_buffer_event_time_stamp process. An attacker can cause incorrect timestamp recording and trigger kernel warnings by racing the attachment of a hist trigger to a buffered event during context switching.
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
