CVE-2025-38591

CVE-2025-38591 affects the Linux kernel and is resolved by a patch in the BPF verifier. The issue involved a narrowing context access check in BPF, where a program attempted to read a pointer field (offset 169) in __sk_buff (field sk at offset 168). The verifier incorrectly allowed this “narrower...
