  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: wl1251: validate packet IDs before indexing tx_frames\n\nwl1251_tx_packet_cb() uses the firmware completion ID directly to index\nthe fixed 16-entry wl-\u003etx_frames[] array. The ID is a raw u8 from the\ncompletion block, and the callback does not currently verify that it\nfits the array before dereferencing it.\n\nReject completion IDs that fall outside wl-\u003etx_frames[] and keep the\nexisting NULL check in the same guard. This keeps the fix local to the\ntrust boundary and avoids touching the rest of the completion flow.",
