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","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"}]}]}],"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"}}}}
