{"id":"CVE-2026-99045","summary":"ibmveth: h_free logical LAN on open-fail after register","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nibmveth: h_free logical LAN on open-fail after register\n\nibmveth_open() registers the logical LAN, then allocates the RX\nbuffer pools. A pool failure jumps to out_free_buffer_pools without\nh_free_logical_lan(), so PHYP still owns the buffer-list page when\nit is unmapped. request_irq() failure already issued the hypercall\nbefore taking the same label.\n\nMove that h_free to the shared post-register unwind so both paths\nderegister before the buffer list is unmapped.","modified":"2026-11-01T02:32:28.521184710Z","published":"2026-10-23T12:22:09.352Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/99xxx/CVE-2026-99045.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/073df7871a7023298ce27cfa518fbc30cc155651"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7bd67d324d952101b3431c796d79f5e329bba159"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a065bd31ec462f6f9c267026b708dd020f122723"},{"type":"WEB","url":"https://git.kernel.org/stable/c/af0524bf4ce1a4cbd2946aa81751582951cfcab5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c54bbdf6f0731102a4bf7f5e4ee535b3ea415996"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d24fdec1413c656d29298097926e77542785ca0c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/decb4d4ead2c71ef698727734ab5024a872eb372"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eae138e880686ce19879aa0d158fa3c73516f632"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/99xxx/CVE-2026-99045.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-99045"},{"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":"d43732ce021f4244a4c53a45d57ad0c13c30ed94"},{"fixed":"073df7871a7023298ce27cfa518fbc30cc155651"},{"fixed":"7bd67d324d952101b3431c796d79f5e329bba159"},{"fixed":"eae138e880686ce19879aa0d158fa3c73516f632"},{"fixed":"decb4d4ead2c71ef698727734ab5024a872eb372"},{"fixed":"c54bbdf6f0731102a4bf7f5e4ee535b3ea415996"},{"fixed":"a065bd31ec462f6f9c267026b708dd020f122723"},{"fixed":"d24fdec1413c656d29298097926e77542785ca0c"},{"fixed":"af0524bf4ce1a4cbd2946aa81751582951cfcab5"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-99045.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.13.0"},{"fixed":"5.10.273"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.224"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.191"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.160"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.113"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.57"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-99045.json"}}],"schema_version":"1.9.2"}
