{"cve":"CVE-2026-98348","nvd":{"published":"2026-10-06T09:18:27.963","modified":"2026-10-19T10:18:37.357","status":"Received","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","score":7.1},"cwes":[],"references":["https://git.kernel.org/stable/c/14cb425ba1f3a5d849e3bbc3d02d84e0ae195dbb","https://git.kernel.org/stable/c/400b89217058fac672134a0d4092c8493dadb8ad","https://git.kernel.org/stable/c/46aa75291056b6dc5faaf956dffdb3e9662477b0","https://git.kernel.org/stable/c/766268b429ae26d8ca599031fa962b0fe4673120","https://git.kernel.org/stable/c/adb7118b7d2cfd7e8213c17d7d2829f353017754"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-98348","score":0.00247,"percentile":0.15816,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
