Overview
Affected versions of this package are vulnerable to Uncaught Exception in the handling of PMZR_EL0 writes to EL2 in arm64 systems. An attacker can cause the host system to crash by triggering a write to PMZR_EL0 from user space when kernel.perf_user_access=1 is enabled, resulting in a trap to EL2 where no handler exists.
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
