{"id":"CVE-2026-43386","summary":"staging: rtl8723bs: fix potential out-of-bounds read in rtw_restruct_wmm_ie","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: rtl8723bs: fix potential out-of-bounds read in rtw_restruct_wmm_ie\n\nThe current code checks 'i + 5 \u003c in_len' at the end of the if statement.\nHowever, it accesses 'in_ie[i + 5]' before that check, which can lead\nto an out-of-bounds read. Move the length check to the beginning of the\nconditional to ensure the index is within bounds before accessing the\narray.","modified":"2026-07-24T18:43:42.870276399Z","published":"2026-05-08T14:21:32.646Z","related":["SUSE-SU-2026:22742-1","SUSE-SU-2026:22769-1","openSUSE-SU-2026:21388-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43386.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/12cc6e8f8d4245b7b5a408c6fc8ab1d098d67020"},{"type":"WEB","url":"https://git.kernel.org/stable/c/209644e25757c499e1c1f08c071ea0386d4448b6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4dd2d9cf563c54e09d5f7eacf95c5b8f538b513b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6ff2243d5e05a5239e39d4ba61d96b0ea3bf7259"},{"type":"WEB","url":"https://git.kernel.org/stable/c/768f25613a9fe6766d15a4a72979657adfc1c6d8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a75281626fc8fa6dc6c9cc314ee423e8bc45203b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d97fc1b29513010b60fde874c7f0ba816744e18c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e14a1148f02e8cf1ca380d57e4b95ca36c97f45d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43386.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43386"},{"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":"6ff2243d5e05a5239e39d4ba61d96b0ea3bf7259"},{"fixed":"12cc6e8f8d4245b7b5a408c6fc8ab1d098d67020"},{"fixed":"209644e25757c499e1c1f08c071ea0386d4448b6"},{"fixed":"768f25613a9fe6766d15a4a72979657adfc1c6d8"},{"fixed":"e14a1148f02e8cf1ca380d57e4b95ca36c97f45d"},{"fixed":"4dd2d9cf563c54e09d5f7eacf95c5b8f538b513b"},{"fixed":"d97fc1b29513010b60fde874c7f0ba816744e18c"},{"fixed":"a75281626fc8fa6dc6c9cc314ee423e8bc45203b"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43386.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.12.0"},{"fixed":"5.10.253"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.203"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.167"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.130"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.78"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.19"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43386.json"}}],"schema_version":"1.7.5"}
