{"id":"CVE-2026-43346","summary":"ice: ptp: don't WARN when controlling PF is unavailable","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nice: ptp: don't WARN when controlling PF is unavailable\n\nIn VFIO passthrough setups, it is possible to pass through only a PF\nwhich doesn't own the source timer. In that case the PTP controlling PF\n(adapter-\u003ectrl_pf) is never initialized in the VM, so ice_get_ctrl_ptp()\nreturns NULL and triggers WARN_ON() in ice_ptp_setup_pf().\n\nSince this is an expected behavior in that configuration, replace\nWARN_ON() with an informational message and return -EOPNOTSUPP.","modified":"2026-10-28T02:30:30.457234938Z","published":"2026-05-08T13:39:31.930Z","related":["SUSE-SU-2026:23066-1","SUSE-SU-2026:23068-1","SUSE-SU-2026:23221-1","SUSE-SU-2026:23231-1","SUSE-SU-2026:23237-1","SUSE-SU-2026:3130-1","SUSE-SU-2026:3166-1","openSUSE-SU-2026:21555-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43346.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/228497715a162d040df1617e62c3b7d0df54b235"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bb3f21edc7056cdf44a7f7bd7ba65af40741838c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c73f365707d3b1b78b7d16e1f029020d1ae50d0f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e19675b384e9dcaca1bd5e4a67b8ad136eccfbe8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43346.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43346"},{"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":"2f59743be4d9568cad2d9cf697d1b897975421ed"},{"fixed":"228497715a162d040df1617e62c3b7d0df54b235"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e800654e85b5b27966fc6493201f5f8cf658beb6"},{"fixed":"e19675b384e9dcaca1bd5e4a67b8ad136eccfbe8"},{"fixed":"c73f365707d3b1b78b7d16e1f029020d1ae50d0f"},{"fixed":"bb3f21edc7056cdf44a7f7bd7ba65af40741838c"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.12.11"},{"fixed":"6.12.114"}]}],"versions":["v6.12.113","v6.12.112","v6.12.111","v6.12.110","v6.12.109","v6.12.108","v6.12.107","v6.12.106","v6.12.105","v6.12.104","v6.12.103","v6.12.102","v6.12.101","v6.12.100","v6.12.99","v6.12.98","v6.12.97","v6.12.96","v6.12.95","v6.12.94","v6.12.93","v6.12.92","v6.12.91","v6.12.90","v6.12.89","v6.12.88","v6.12.87","v6.12.86","v6.12.85","v6.12.84","v6.12.83","v6.12.82","v6.12.81","v6.12.80","v6.12.79","v6.12.78","v6.12.77","v6.12.76","v6.12.75","v6.12.74","v6.12.73","v6.12.72","v6.12.71","v6.12.70","v6.12.69","v6.12.68","v6.12.67","v6.12.66","v6.12.65","v6.12.64","v6.12.63","v6.12.62","v6.12.61","v6.12.60","v6.12.59","v6.12.58","v6.12.57","v6.12.56","v6.12.55","v6.12.54","v6.12.53","v6.12.52","v6.12.51","v6.12.50","v6.12.49","v6.12.48","v6.12.47","v6.12.46","v6.12.45","v6.12.44","v6.12.43","v6.12.42","v6.12.41","v6.12.40","v6.12.39","v6.12.38","v6.12.37","v6.12.36","v6.12.35","v6.12.34","v6.12.33","v6.12.32","v6.12.31","v6.12.30","v6.12.29","v6.12.28","v6.12.27","v6.12.26","v6.12.25","v6.12.24","v6.12.23","v6.12.22","v6.12.21","v6.12.20","v6.12.19","v6.12.18","v6.12.17","v6.12.16","v6.12.15","v6.12.14","v6.12.13","v6.12.12","v6.12.11"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43346.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.114"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.24"},{"fixed":"6.19.14"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43346.json"}}],"schema_version":"1.9.2"}
