CVE-2023-2163: Incorrect Verifier Branch Pruning Logic Leads To Arbitrary Read/Write In Linux Kernel and Lateral Privilege Escalation

First published: Fri Jun 30 2023(Updated: )

Incorrect verifier pruning in BPF in Linux Kernel &gt;=5.4 leads to unsafe code paths being incorrectly marked as safe, resulting in arbitrary read/write in kernel memory, lateral privilege escalation, and container escape. Reference and upstream patch: <a href="https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=71b547f561247897a0a14f3082730156c0533fed">https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=71b547f561247897a0a14f3082730156c0533fed</a>
