  "details": "In the Linux kernel, the following vulnerability has been resolved:  bpf: Check params size before reading reserved fields  bpf_crypto_ctx_create() is a kfunc whose second argument is declared with the __sz annotation, so the verifier only guarantees that params__sz bytes of params are valid.  The function nevertheless reads params-\u003ereserved[0] and params-\u003ereserved[1] (offsets 14 and 15) before comparing params__sz against the size of struct bpf_crypto_params, so a BPF program can pass a shorter buffer and have the kernel read past the region that was validated for it.  Move the size check in front of the reserved field reads.",
