{"id":"CVE-2026-98155","summary":"accel/qaic: Address potential out-of-bounds read in resp_worker()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\naccel/qaic: Address potential out-of-bounds read in resp_worker()\n\nAlthough 'commit 2feec5ae5df7 (\"accel/qaic: Handle DBC deactivation if the\nowner went away\")' fixes the scenario it was intended for by walking the\nmessage and only decoding QAIC_TRANS_DEACTIVATE_FROM_DEV, if present, it\nskipped over the bounds checking code that is included in decode_message().\nThis could lead to issues such as reading past the slab allocation's end,\ninfinite loops or kernel panics. For those issues to happen, a malformed\nwire message is needed to be sent from the device.\n\nInstead of duplicating the bounds checking code already present in\ndecode_message(), use the function inside resp_worker().","modified":"2026-11-13T04:07:26.907545112Z","published":"2026-09-25T10:36:25.812Z","related":["SUSE-SU-2026:24550-1","SUSE-SU-2026:24619-1","SUSE-SU-2026:24643-1","SUSE-SU-2026:24648-1","SUSE-SU-2026:24651-1","SUSE-SU-2026:24662-1","SUSE-SU-2026:5091-1","openSUSE-SU-2026:12074-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98155.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/12deeade460d47031267256ba07add51cc7eabd0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5807a65f301b6c0e73a2dc03dd6f5e80a2861b72"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ab243f74ab4084ca5c8dec608cb5b0deb27db067"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c72e81ee46bdd4c221114d6e9515e9b4647616d7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f4b64488f3deca63f7fbc7d7c3835b2e668003f9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98155.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98155"},{"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":"2dd67966f39a2abf8ccb4865031c722e40e01b7f"},{"fixed":"5807a65f301b6c0e73a2dc03dd6f5e80a2861b72"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"08021f2d4a557d6491e3bcc288e96425f50aa3cf"},{"fixed":"f4b64488f3deca63f7fbc7d7c3835b2e668003f9"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"f403094d9075d7c565a3d81002b781c325cb3c07"},{"fixed":"12deeade460d47031267256ba07add51cc7eabd0"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"2feec5ae5df785658924ab6bd91280dc3926507c"},{"fixed":"c72e81ee46bdd4c221114d6e9515e9b4647616d7"},{"fixed":"ab243f74ab4084ca5c8dec608cb5b0deb27db067"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"ee0180e77e6c8482644569632065411de844c515"}]}],"versions":["v6.6.157","v6.6.156","v6.6.155","v6.6.154","v6.6.153","v6.6.152","v6.6.151","v6.6.150","v6.6.149","v6.6.148","v6.6.147","v6.6.146","v6.6.145","v6.6.144","v6.6.143","v6.6.142","v6.6.141","v6.6.140","v6.6.139","v6.6.138","v6.6.137","v6.6.136","v6.6.135","v6.6.134","v6.12.110","v6.12.109","v6.12.108","v6.12.107","v6.12.106","v6.12.105","v6.12.104","v6.12.103","v6.12.102","v6.12.101","v6.12.100","v6.12.99","v6.12.98","v6.12.97","v6.12.96","v6.12.95","v6.12.94","v6.12.93","v6.12.92","v6.12.91","v6.12.90","v6.12.89","v6.12.88","v6.12.87","v6.12.86","v6.12.85","v6.12.84","v6.12.83","v6.12.82","v6.12.81","v6.18.52","v6.18.51","v6.18.50","v6.18.49","v6.18.48","v6.18.47","v6.18.46","v6.18.45","v6.18.44","v6.18.43","v6.18.42","v6.18.41","v6.18.40","v6.18.39","v6.18.38","v6.18.37","v6.18.36","v6.18.35","v6.18.34","v6.18.33","v6.18.32","v6.18.31","v6.18.30","v6.18.29","v6.18.28","v6.18.27","v6.18.26","v6.18.25","v6.18.24","v6.18.23","v6.18.22","v6.19.14","v6.19.13","v6.19.12"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98155.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.6.134"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.12.81"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.18.22"},{"fixed":"6.18.53"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.12"},{"fixed":"6.20"}]},{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.2.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98155.json"}}],"schema_version":"1.9.2"}
