Overview

Affected versions of this package are vulnerable to Uncaught Exception due to improper handling of arena-related instructions in the __bpf_prog_select_runtime process. An attacker can trigger a kernel crash by executing BPF programs that use arena ST/LDX/STX instructions, causing the interpreter to encounter an unsupported opcode and hit a BUG_ON() at runtime.

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
