This writes lq_color into a random tid_data\nslot unrelated to the BA entry.\nSince multi-TID blockack is not really in use, 'i' was always 0 and no\nharm was done.\nAdd a out-of-bound check before accessing the array.","modified":"2026-11-04T14:27:21.813679608Z","published":"2026-09-24T16:02:24.091Z","related":["SUSE-SU-2026:5091-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93790.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/35f991d685feafd27255bd33272512c434e52527"},{"type":"WEB","url":"https://git.kernel.org/stable/c/94d3982806c7f194b23484befde12934dda23064"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c48b741277b01b2c3b4ecccedc72fc575b71dc04"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e8ac5e91b1296f65c3d119fac3fa917ff458f811"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ed9869e64dd7a397a320ae7a37f1e4a36f866f74"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93790.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93790"},{"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":"41fd2fec56db2564f02532ed7244e1f69193b4ad"},{"fixed":"ed9869e64dd7a397a320ae7a37f1e4a36f866f74"},{"fixed":"35f991d685feafd27255bd33272512c434e52527"},{"fixed":"c48b741277b01b2c3b4ecccedc72fc575b71dc04"},{"fixed":"e8ac5e91b1296f65c3d119fac3fa917ff458f811"},{"fixed":"94d3982806c7f194b23484befde12934dda23064"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-93790.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"6.1.191"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-93790.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
