Overview
Affected versions of this package are vulnerable to Open Redirect in the BPF verifier's precision tracking process. An attacker can achieve arbitrary kernel memory read and write, escalate privileges to root, and cause kernel crashes by loading a specially crafted BPF program through the local bpf syscall that exploits incorrect state pruning and stack spill/fill handling.
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
