{"apiVersion":"1.0","identifier":"CVE-2026-74334","description":"In the Linux kernel, the following vulnerability has been resolved: RDMA/nldev: Fix locking when accessing mr->pd Sashiko points out that, due to rereg_mr, the PD is actually variable and all the touches in nldev are racy. Use mr->device instead of mr->pd->device. Getting the PD restrack ID is more tricky. To avoid disturbing all the happy paths, add an rdma_restrack_sync() operation which is sort of like flush_workqueue() or synchronize_irq(): after it returns, all the old nldev touches to the mr are gone and everything sees the new PD. This makes it safe to reach into the PD pointer.","publishedAt":"2026-08-15T06:22:34","lastModifiedAt":"2026-08-17T06:19:27","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74334","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.0012,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74334","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74334","en":"https://www.redsauce.net/en/cves/CVE-2026-74334","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74334","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74334","de":"https://www.redsauce.net/de/cves/CVE-2026-74334","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74334","el":"https://www.redsauce.net/el/cves/CVE-2026-74334"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74334"}}
