Overview

Affected versions of this package are vulnerable to Remote Code Execution (RCE) due to improper restoration of user AMR values in the arch_exit_to_user_mode_prepare function. An attacker can execute arbitrary code in kernel context by exploiting the premature restoration of access permissions during the transition from kernel to user mode.

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
