A still-pending q_work then runs\nqla_do_work() against the freed qpair and response queue, causing a\nuse-after-free. This is especially likely during full adapter teardown,\nwhere destroy_workqueue(ha->wq) forces pending work to run after the queue\npairs have been freed.\n\nFlush the work item with cancel_work_sync() in qla25xx_free_rsp_que()\nafter free_irq() has released the interrupt (so no new work can be\nqueued) and before the response queue and qpair memory are freed (so the\nflushed handler still sees valid memory). Guard on rsp->qpair and ha->wq\nto match the INIT_WORK() condition and avoid operating on an\nuninitialized work_struct.","score":7.5,"severity":"high","published":"2026-09-25T10:21:34.991Z","modified":"2026-10-30T12:37:16.823Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"68ca949cdb04b4dc71451a999148fbc5f187a220","status":"affected","lessThan":"2089647f81ff5263867ec08589f273899016ad4a","versionType":"git"},{"version":"68ca949cdb04b4dc71451a999148fbc5f187a220","status":"affected","lessThan":"bf3f802619eb57cb11c706263dca13255db9f3fd","versionType":"git"},{"version":"68ca949cdb04b4dc71451a999148fbc5f187a220","status":"affected","lessThan":"942ceba876881a57e5157bb30a8a05f99a77ddd8","versionType":"git"},{"version":"68ca949cdb04b4dc71451a999148fbc5f187a220","status":"affected","lessThan":"9bd063c082ef0475dfc28c46f607aa3e90fe13d7","versionType":"git"},{"version":"68ca949cdb04b4dc71451a999148fbc5f187a220","status":"affected","lessThan":"dd6c14db0dbb7774278e62c8114902f953540932","versionType":"git"},{"version":"68ca949cdb04b4dc71451a999148fbc5f187a220","status":"affected","lessThan":"1710a69fd74d0b4bdfcc57c3309b1c4057f70d85","versionType":"git"},{"version":"68ca949cdb04b4dc71451a999148fbc5f187a220","status":"affected","lessThan":"f1f4d1cb93eeeb250eac9405121933e268eefbd3","versionType":"git"},{"version":"68ca949cdb04b4dc71451a999148fbc5f187a220","status":"affected","lessThan":"19788a55cab61d78e33e0914a5a31d27843e8a4a","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-97536"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"2.6.31","status":"affected"},{"version":"0","status":"unaffected","lessThan":"2.6.31","versionType":"semver"},{"version":"5.10.273","status":"unaffected","lessThanOrEqual":"5.10.*","versionType":"semver"},{"version":"5.15.224","status":"unaffected","lessThanOrEqual":"5.15.*","versionType":"semver"},{"version":"6.1.191","status":"unaffected","lessThanOrEqual":"6.1.*","versionType":"semver"},{"version":"6.6.160","status":"unaffected","lessThanOrEqual":"6.6.*","versionType":"semver"},{"version":"6.12.112","status":"unaffected","lessThanOrEqual":"6.12.*","versionType":"semver"},{"version":"6.18.53","status":"unaffected","lessThanOrEqual":"6.18.*","versionType":"semver"},{"version":"7.2.7","status":"unaffected","lessThanOrEqual":"7.2.*","versionType":"semver"},{"version":"7.3","status":"unaffected","lessThanOrEqual":"*","versionType":"original_commit_for_fix"}],"defaultStatus":"affected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-97536"}],"remediation":[],"references":["https://git.kernel.org/stable/c/2089647f81ff5263867ec08589f273899016ad4a","https://git.kernel.org/stable/c/bf3f802619eb57cb11c706263dca13255db9f3fd","https://git.kernel.org/stable/c/942ceba876881a57e5157bb30a8a05f99a77ddd8","https://git.kernel.org/stable/c/9bd063c082ef0475dfc28c46f607aa3e90fe13d7","https://git.kernel.org/stable/c/dd6c14db0dbb7774278e62c8114902f953540932","https://git.kernel.org/stable/c/1710a69fd74d0b4bdfcc57c3309b1c4057f70d85","https://git.kernel.org/stable/c/f1f4d1cb93eeeb250eac9405121933e268eefbd3","https://git.kernel.org/stable/c/19788a55cab61d78e33e0914a5a31d27843e8a4a"],"sources":[{"name":"CVE","id":"CVE-2026-97536","modified":"2026-10-30T12:37:16.823Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-97536"}],"assessments":[{"source":"Linux","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":7.5}],"sourceAffected":[],"observedAt":"2026-10-30T13:58:15.699Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T00:05:31.288Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
