CVE-2026-74344

CVE-2026-74344 affects the Linux kernel BPF RB-tree code. The vulnerability arises in bpf_rb_root_free() when detaching the root: the function copies rb_root_cached, replaces the live root with RB_ROOT_CACHED, and then walks the copied tree to drop objects. If a dropped object is refcounted and s...
