{"id":"CVE-2026-72329","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-72329","summary":"net/liquidio: drop cached VF pci_dev LUT","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/liquidio: drop cached VF pci_dev LUT\n\nThe PF SR-IOV enable path caches VF pci_dev pointers in\ndpiring_to_vfpcidev_lut[] by iterating with pci_get_device(). Those\nentries do not own a reference, because the iterator drops the previous\ndevice reference on each step. The cached pointer is then dereferenced\nlater when handling OCTEON_VF_FLR_REQUEST.\n\nReplace the cached VF mapping with runtime lookup on the mailbox DPI\nring: derive the VF index from q_no, resolve the VF via exported PCI\nIOV helpers, validate it with the PF pointer and VF ID, then issue\npcie_flr() and drop the reference with pci_dev_put(). Remove the\nunused VF lookup table initialization and cleanup.","published":"2026-08-15T05:55:39.931Z","modified":"2026-08-16T03:48:40.037879838Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"7.1.5"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5c0e3ba4f500fd4314ceb42f07f16bc445156431"},{"type":"WEB","url":"https://git.kernel.org/stable/c/81acef3a247fd523513a2e9f71de1c167bc0f882"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72329.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72329"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-16T03:48:40.037879838Z"}}
