Overview

Affected versions of this package are vulnerable to Buffer Overflow in the trace_event_raw_event_synth process. An attacker can cause a kernel crash or execute arbitrary code by creating and enabling synthetic events with stacktrace fields that are improperly handled as normal fields.

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
