CVE-2026-43333
CVE-2026-43333 (Linux kernel BPF): The vulnerability arises from direct dereference of nullable PTR_TO_BUF pointers in check_mem_access(), where PTR_TO_BUF is matched via base_type() after PTR_MAYBE_NULL stripping, allowing NULL dereferences in map iterators ctx->key/value (NULL on stop callba...
