{"id":"CVE-2026-64444","summary":"staging: rtl8723bs: fix OOB read in OnAssocRsp() IE loop","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: rtl8723bs: fix OOB read in OnAssocRsp() IE loop\n\nThe IE parsing loop in OnAssocRsp() advances by (pIE-\u003elength + 2) each\niteration but only guards on i \u003c pkt_len. When a malicious AP sends an\nAssocResponse whose last IE has only one byte remaining in the frame\n(the element_id byte lands at pkt_len-1), the loop reads pIE-\u003elength\nfrom pframe[pkt_len], which is one byte past the allocated receive buffer.\n\nAdditionally, even when the header bytes are in bounds, pIE-\u003elength\nitself can extend the data window beyond pkt_len, silently passing a\ntruncated IE to the handler functions.\n\nAdd two guards at the top of the loop body:\n  1. Break if fewer than sizeof(*pIE) bytes remain (can't read header).\n  2. Break if the IE's declared data extends past pkt_len.","modified":"2026-07-28T04:03:07.258952229Z","published":"2026-07-25T08:51:15.968Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64444.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0406d746574e875d8778552eb674fcfbf5330bfb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/04f612dc03427e0b1ac80a2611b5ac0ba93ac446"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0970dd47726a57e52013594e9fbf667586eb3673"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1a52a05471494546f955a58e8c170c0c796c52d5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7e7741c8315e4160aead00a60cdd6f81ab880717"},{"type":"WEB","url":"https://git.kernel.org/stable/c/889ca6000ac7fa73457b041848fcb08e0d51b809"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f9654207e92283e0acac5d64fe5f8835383b5a23"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64444.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64444"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"554c0a3abf216c991c5ebddcdb2c08689ecd290b"},{"fixed":"889ca6000ac7fa73457b041848fcb08e0d51b809"},{"fixed":"1a52a05471494546f955a58e8c170c0c796c52d5"},{"fixed":"0406d746574e875d8778552eb674fcfbf5330bfb"},{"fixed":"0970dd47726a57e52013594e9fbf667586eb3673"},{"fixed":"04f612dc03427e0b1ac80a2611b5ac0ba93ac446"},{"fixed":"7e7741c8315e4160aead00a60cdd6f81ab880717"},{"fixed":"f9654207e92283e0acac5d64fe5f8835383b5a23"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64444.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.12.0"},{"fixed":"5.15.212"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.96"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.39"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64444.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"}]}
