{"cve":"CVE-2026-68196","nvd":{"published":"2026-08-10T13:20:07.023","modified":"2026-08-19T17:20:35.820","status":"Received","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: wilc1000: validate assoc response length before subtracting header\n\nwilc_parse_assoc_resp_info() computes the trailing IE length as\n\n\ties_len = buffer_len - sizeof(*res);\n\nwithout first checking that buffer_len is at least sizeof(struct\nwilc_assoc_resp) (6 bytes). buffer_len is the length reported for a\nreceived association response (host_int_parse_assoc_resp_info() passes\nhif_drv->assoc_resp / assoc_resp_info_len straight in) and must be\nvalidated before the driver accesses the fixed header.\n\nFor a frame shorter than the 6-byte fixed header, the subtraction wraps.\nFor a four-byte response the result is truncated to a u16 ies_len of\n65534, so kmemdup() then attempts to copy 65534 bytes starting at\nbuffer + sizeof(*res), beyond the valid association-response data\n(CWE-125). A response shorter than four bytes can also cause an\nout-of-bounds read of res->status_code at offsets 2 and 3.\n\nReject frames too short to hold the fixed header before touching the\nheader or computing ies_len. Also set the connection status to a failure\non this path: the caller falls through to a\n\"conn_info->status == WLAN_STATUS_SUCCESS\" check after the parser\nreturns, so leaving the status untouched could let a malformed short\nresponse be treated as a successful association.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:H","score":8.3},"cwes":[],"references":["https://git.kernel.org/stable/c/4c4c97b60a5e978121d9ee8cb0ab3916e5d6a8de","https://git.kernel.org/stable/c/4d410320e8ae5933e651660c9fadc1d380309e23","https://git.kernel.org/stable/c/584c8954ad55f8b09b475be6db710fe40ceb988c","https://git.kernel.org/stable/c/8ccdf8c8de87a9580df37c3c1ec53ba88cedef65","https://git.kernel.org/stable/c/8d50acf5420de0c4da99c2d634731c9d3164a755"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68196","score":0.00413,"percentile":0.35664,"date":"2026-10-31"},"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).
