{"id":"AZL-96486","summary":"CVE-2026-74334 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/nldev: Fix locking when accessing mr-\u003epd\n\nSashiko points out that, due to rereg_mr, the PD is actually variable and\nall the touches in nldev are racy.\n\nUse mr-\u003edevice instead of mr-\u003epd-\u003edevice.\n\nGetting the PD restrack ID is more tricky. To avoid disturbing all the\nhappy paths, add an rdma_restrack_sync() operation which is sort of like\nflush_workqueue() or synchronize_irq(): after it returns, all the old\nnldev touches to the mr are gone and everything sees the new PD. This\nmakes it safe to reach into the PD pointer.","modified":"2026-09-02T06:51:55Z","published":"2026-08-15T06:22:34Z","upstream":["CVE-2026-74334"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74334"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-96486.json"}}],"schema_version":"1.9.0"}
