CVE-2024-50253

CVE-2024-50253 affects the Linux kernel’s BPF interpreter, specifically the bpf_iter_bits_new() path in kernel/bpf/helpers.c. The root cause is an overflow in nr_words that can cause stack corruption via bpf_probe_read_kernel_common() when nr_bits overflows (e.g., nr_words = 0x0400-0001). The doc...
