CVE-2023-54181

CVE-2023-54181 concerns the Linux kernel BPF verifier: after migrating networking-bpf capabilities from cap_sys_admin to cap_net_admin+cap_bpf, the verifier incorrectly flagged a two-pointer comparison as a leak, blocking program startup. A patch fixes the allow_ptr_leaks check, addressing the fa...

CVE-2022-50650

A flaw was found in the Linux kernel's BPF verifier. The verifier incorrectly handles reference state management for synchronous callbacks that execute multiple times foreach style helpers. This can lead to reference leaks when callbacks acquire references, or double-free conditions when callback...
