{"id":"CVE-2026-68190","summary":"staging: rtl8723bs: fix OOB reads in rtw_get_wps_ie()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: rtl8723bs: fix OOB reads in rtw_get_wps_ie()\n\nrtw_get_wps_ie() iterates over IE data from network frames without\nvalidating that the IE header and payload fit within the remaining\nbuffer before reading them. Specifically:\n\n- in_ie[cnt + 1] is read without checking cnt + 1 \u003c in_len\n- memcmp(&in_ie[cnt + 2], ...) accesses cnt + 2 without bounds check\n- in_ie[cnt + 1] is used as length without verifying payload fits\n\nAdd bounds checks at the top of the loop body to break early if fewer\nthan 2 bytes remain for the IE header, or if the declared payload\nextends past the end of the buffer. Also require at least 4 bytes of\npayload before comparing the WPS OUI.","modified":"2026-08-18T03:31:12.972390438Z","published":"2026-08-10T12:00:07.764Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68190.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0e95ff792ae0aa6fbad9455943e9e1e4062670e9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/23c31f107b4f8f420a754a45d12599bdb78f9bb8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/630fdca3f2437fee3ffd437c4b646ccf84c7be87"},{"type":"WEB","url":"https://git.kernel.org/stable/c/875479f18835ac11e21a83e88f3d4dc7ccdcd0c4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b9d9a4cd2e59df7281992a076464d2536e80c674"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68190.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68190"},{"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":"b9d9a4cd2e59df7281992a076464d2536e80c674"},{"fixed":"630fdca3f2437fee3ffd437c4b646ccf84c7be87"},{"fixed":"875479f18835ac11e21a83e88f3d4dc7ccdcd0c4"},{"fixed":"23c31f107b4f8f420a754a45d12599bdb78f9bb8"},{"fixed":"0e95ff792ae0aa6fbad9455943e9e1e4062670e9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68190.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.12.0"},{"fixed":"6.6.148"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68190.json"}}],"schema_version":"1.9.0"}
