This ordering allows two paths to queue work on the\ndestroyed workqueue:\n\n1. If pdsc_teardown() -> pdsc_devcmd_reset() times out, the error\n path in pdsc_devcmd_locked() queues health_work.\n\n2. A NotifyQ event can trigger the ISR and queue work before free_irq()\n is called in pdsc_teardown().\n\nFix by moving destroy_workqueue() after pdsc_teardown() so the\nworkqueue outlives every queuer; destroy_workqueue() then flushes any\nwork still pending.\n\nDraining the queued work also requires ordering the teardown so the\nresources that work touches are freed last:\n\n - In pdsc_qcq_free(), after freeing the interrupt, cancel_work_sync()\n the queue's work and only then clear qcq->intx, so\n pdsc_process_adminq()'s read of qcq->intx for interrupt-credit\n return cannot race with the clear.\n\n - Free adminqcq before notifyqcq: the shared adminq ISR is released\n when adminqcq is freed, and the adminq work accesses notifyqcq, so\n both must be stopped before notifyqcq is freed."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/amd/pds_core/core.c", "drivers/net/ethernet/amd/pds_core/main.c"], "versions": [{"version": "01ba61b55b2041a39c54aefb3153c770dd59a0ef", "lessThan": "224214eb4182ff20a665b615a90b66017539dd75", "status": "affected", "versionType": "git"}, {"version": "01ba61b55b2041a39c54aefb3153c770dd59a0ef", "lessThan": "9e0f80fac50ab95dd75537c8ecaf5051d01f19b5", "status": "affected", "versionType": "git"}, {"version": "01ba61b55b2041a39c54aefb3153c770dd59a0ef", "lessThan": "ecc7a7d7569ec1d6a61e18372696b9de97635156", "status": "affected", "versionType": "git"}, {"version": "01ba61b55b2041a39c54aefb3153c770dd59a0ef", "lessThan": "0ad134881508c36b65c1a8864f8bec53adbd3327", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/amd/pds_core/core.c", "drivers/net/ethernet/amd/pds_core/main.c"], "versions": [{"version": "6.4", "status": "affected"}, {"version": "0", "lessThan": "6.4", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.101", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.42", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1.6", "lessThanOrEqual": "7.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2-rc5", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "6.12.101"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "6.18.42"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "7.1.6"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "7.2-rc5"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/224214eb4182ff20a665b615a90b66017539dd75"}, {"url": "https://git.kernel.org/stable/c/9e0f80fac50ab95dd75537c8ecaf5051d01f19b5"}, {"url": "https://git.kernel.org/stable/c/ecc7a7d7569ec1d6a61e18372696b9de97635156"}, {"url": "https://git.kernel.org/stable/c/0ad134881508c36b65c1a8864f8bec53adbd3327"}], "title": "pds_core: fix use-after-free on workqueue during remove", "x_generator": {"engine": "bippy-1.2.0"}}}}
