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.","state":0,"publishedAt":"2026-10-06T08:46:36.927+00:00","modifiedAt":"2026-10-19T09:17:59.174+00:00","affected":[{"ecosystem":"Vendor
