{"id":"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.","modified":"2026-08-18T03:56:23.559132762Z","published":"2026-08-15T05:55:39.931Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72329.json","cna_assigner":"Linux"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"ca6139ffc67ee6ef0459f81e37894ed411083855"},{"fixed":"81acef3a247fd523513a2e9f71de1c167bc0f882"},{"fixed":"5c0e3ba4f500fd4314ceb42f07f16bc445156431"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72329.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.10.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72329.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
