{"id":"CVE-2026-23013","summary":"net: octeon_ep_vf: fix free_irq dev_id mismatch in IRQ rollback","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: octeon_ep_vf: fix free_irq dev_id mismatch in IRQ rollback\n\noctep_vf_request_irqs() requests MSI-X queue IRQs with dev_id set to\nioq_vector. If request_irq() fails part-way, the rollback loop calls\nfree_irq() with dev_id set to 'oct', which does not match the original\ndev_id and may leave the irqaction registered.\n\nThis can keep IRQ handlers alive while ioq_vector is later freed during\nunwind/teardown, leading to a use-after-free or crash when an interrupt\nfires.\n\nFix the error path to free IRQs with the same ioq_vector dev_id used\nduring request_irq().","modified":"2026-05-15T11:53:30.352219745Z","published":"2026-01-25T14:36:26.208Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23013.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/aa05a8371ae4a452df623f7202c72409d3c50e40"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aa4c066229b05fc3d3c5f42693d25b1828533b6e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f93fc5d12d69012788f82151bee55fce937e1432"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23013.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23013"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.9.0"},{"fixed":"6.12.67"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-23013.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
