{"id":"CVE-2023-53850","summary":"iavf: use internal state to free traffic IRQs","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niavf: use internal state to free traffic IRQs\n\nIf the system tries to close the netdev while iavf_reset_task() is\nrunning, __LINK_STATE_START will be cleared and netif_running() will\nreturn false in iavf_reinit_interrupt_scheme(). This will result in\niavf_free_traffic_irqs() not being called and a leak as follows:\n\n    [7632.489326] remove_proc_entry: removing non-empty directory 'irq/999', leaking at least 'iavf-enp24s0f0v0-TxRx-0'\n    [7632.490214] WARNING: CPU: 0 PID: 10 at fs/proc/generic.c:718 remove_proc_entry+0x19b/0x1b0\n\nis shown when pci_disable_msix() is later called. Fix by using the\ninternal adapter state. The traffic IRQs will always exist if\nstate == __IAVF_RUNNING.","modified":"2026-03-31T17:29:30.586369Z","published":"2025-12-09T01:30:14.740Z","related":["SUSE-SU-2026:0263-1","SUSE-SU-2026:0278-1","SUSE-SU-2026:0281-1","SUSE-SU-2026:0293-1","SUSE-SU-2026:0315-1","SUSE-SU-2026:0316-1","SUSE-SU-2026:0317-1","SUSE-SU-2026:0411-1","SUSE-SU-2026:0617-1","SUSE-SU-2026:20477-1","SUSE-SU-2026:20498-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53850.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5e9db32eec628481f5da97a5b1aedb84a5240d18"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6d9d01689b82ff5cb8f8d2a82717d7997bc0bfff"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a77ed5c5b768e9649be240a2d864e5cd9c6a2015"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53850.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53850"},{"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":"5b36e8d04b4439c9ceb814bfdfe1284737f9c632"},{"fixed":"6d9d01689b82ff5cb8f8d2a82717d7997bc0bfff"},{"fixed":"5e9db32eec628481f5da97a5b1aedb84a5240d18"},{"fixed":"a77ed5c5b768e9649be240a2d864e5cd9c6a2015"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-53850.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"6.1.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.4.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-53850.json"}}],"schema_version":"1.7.5"}
