  "summary": "wifi: libipw: reject too-short association responses",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: libipw: reject too-short association responses\n\nlibipw_handle_assoc_resp() reads the capability, status and aid fields\nof the 30-byte association response prefix and then computes the\ninformation element length as\n\n\tstats->len - sizeof(*frame)\n\nstats->len is a u16 and sizeof() has type size_t, so the subtraction is\nevaluated as size_t and wraps instead of going negative.  Truncating\nthat to the u16 length parameter of libipw_parse_info_param() turns a\nframe shorter than the fixed fields into a length near 64 KiB, and the\nparser then reads past the receive buffer.\n\nBoth the ipw2100 and ipw2200 management receive paths reach this\nfunction having established only that the frame carries the generic\n24-byte three-address header.\n\nReject the frame before any fixed field is touched.\n\nFound by an AI-assisted review of length arithmetic in management frame\nparsers.  Verified with a KUnit case under Generic KASAN on arm64 under\nQEMU; I do not have the hardware, so it is not tested on a real device.",
