How to fix?

Overview

Affected versions of this package are vulnerable to Improper Input Validation in the bpf_map_check_op_flags process. An attacker can read or write arbitrary kernel memory by supplying a crafted CPU ID in the upper 32 bits of the map operation flags during BPF map update or lookup operations. This can lead to kernel memory corruption or leakage through direct system calls from userspace.

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
