Additionally, rtw_get_sec_ie()\ncompares the 4-byte WPA OUI at cnt+2 without checking that at least\n6 bytes remain, and rtw_get_wapi_ie() compares a 4-byte WAPI OUI at\ncnt+6 without checking that at least 10 bytes remain.\n\nrtw_get_wps_attr() reads wps_ie[0] and wps_ie+2 unconditionally at\nentry, before verifying that wps_ielen is large enough to contain\nthe 6-byte WPS IE header (element_id + length + 4-byte OUI). Inside\nthe attribute loop, get_unaligned_be16() is called on attr_ptr and\nattr_ptr+2 without checking that 4 bytes remain in the buffer.\n\nAdd a cnt+2 bounds check before each loop body in rtw_get_sec_ie()\nand rtw_get_wapi_ie(), guard each multi-byte comparison with a minimum\nIE length requirement, add a wps_ielen < 6 early return in\nrtw_get_wps_attr(), and add a 4-byte bounds check in its inner loop.","state":0,"publishedAt":"2026-07-25T08:51:13.834+00:00","modifiedAt":"2026-10-19T20:38:29.338+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"unaffected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/staging/rtl8723bs/core/rtw_ieee80211.c\"\n ],\n \"versions\": [\n {\n \"version\": \"554c0a3abf216c991c5ebddcdb2c08689ecd290b\",\n \"lessThan\": \"efa27d487abcdec79669a60a6d94d5d6eceb7c1d\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"554c0a3abf216c991c5ebddcdb2c08689ecd290b\",\n \"lessThan\": \"2ea1ce30ead61589214240e8d33d96310fd613e5\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"554c0a3abf216c991c5ebddcdb2c08689ecd290b\",\n \"lessThan\": \"b27ecba3196f6c14e3809595ebd69c0c2392512a\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"554c0a3abf216c991c5ebddcdb2c08689ecd290b\",\n \"lessThan\": \"6ab1161e539fb7a1c8b35ff5a6ced4702e855b9c\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"554c0a3abf216c991c5ebddcdb2c08689ecd290b\",\n \"lessThan\": \"4b51ee8a40fe47864197d73cc02b191de7a6b072\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"554c0a3abf216c991c5ebddcdb2c08689ecd290b\",\n \"lessThan\": \"729c4e72563bda0f1725db1db9ea08df06f41d9b\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"554c0a3abf216c991c5ebddcdb2c08689ecd290b\",\n \"lessThan\": \"1463ca3ec6601cbb097d8d87dbf5dcf1cb86a344\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n }\n ]\n }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"affected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/staging/rtl8723bs/core/rtw_ieee80211.c\"\n ],\n \"versions\": [\n {\n \"version\": \"4.12\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"4.12\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.212\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.178\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.145\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.97\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.40\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.1.4\",\n \"lessThanOrEqual\": \"7.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.2\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/efa27d487abcdec79669a60a6d94d5d6eceb7c1d","https://git.kernel.org/stable/c/2ea1ce30ead61589214240e8d33d96310fd613e5","https://git.kernel.org/stable/c/b27ecba3196f6c14e3809595ebd69c0c2392512a","https://git.kernel.org/stable/c/6ab1161e539fb7a1c8b35ff5a6ced4702e855b9c","https://git.kernel.org/stable/c/4b51ee8a40fe47864197d73cc02b191de7a6b072","https://git.kernel.org/stable/c/729c4e72563bda0f1725db1db9ea08df06f41d9b","https://git.kernel.org/stable/c/1463ca3ec6601cbb097d8d87dbf5dcf1cb86a344"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-64441","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-64441","identifiers":["CVE-2026-64441"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
