CVE-2024-49861

CVE-2024-49861 affects the Linux kernel: bpf: Fix helper writes to read-only maps. The issue allowed a BPF program to write into a read‑only map (e.g., frozen .rodata) via helpers using ARG_PTR_TO_{LONG,INT}, because meta->raw_mode wasn’t set and check_map_access_type() treated the map as read...
