"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Check params size before reading reserved fields\n\nbpf_crypto_ctx_create() is a kfunc whose second argument is declared\nwith the __sz annotation, so the verifier only guarantees that\nparams__sz bytes of params are valid. The function nevertheless reads\nparams->reserved[0] and params->reserved[1] (offsets 14 and 15) before\ncomparing params__sz against the size of struct bpf_crypto_params, so a\nBPF program can pass a shorter buffer and have the kernel read past the\nregion that was validated for it.\n\nMove the size check in front of the reserved field reads."
