{"apiVersion":"1.0","identifier":"CVE-2026-72329","description":"In the Linux kernel, the following vulnerability has been resolved: net/liquidio: drop cached VF pci_dev LUT The PF SR-IOV enable path caches VF pci_dev pointers in dpiring_to_vfpcidev_lut[] by iterating with pci_get_device(). Those entries do not own a reference, because the iterator drops the previous device reference on each step. The cached pointer is then dereferenced later when handling OCTEON_VF_FLR_REQUEST. Replace the cached VF mapping with runtime lookup on the mailbox DPI ring: derive the VF index from q_no, resolve the VF via exported PCI IOV helpers, validate it with the PF pointer and VF ID, then issue pcie_flr() and drop the reference with pci_dev_put(). Remove the unused VF lookup table initialization and cleanup.","publishedAt":"2026-08-15T06:22:05","lastModifiedAt":"2026-08-17T06:18:36","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72329","cvssScore":9.3,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","epssProbability":0.0018,"riskScore":0.95,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72329","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72329","en":"https://www.redsauce.net/en/cves/CVE-2026-72329","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72329","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72329","de":"https://www.redsauce.net/de/cves/CVE-2026-72329","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72329","el":"https://www.redsauce.net/el/cves/CVE-2026-72329"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72329"}}
