However, it frees the VSI before reading the\nindex for the erase, resulting in a use-after-free.\n\nFollow the reverse of the allocation order in ice_alloc_dynamic_port()\nby erasing the xarray entry before freeing the VSI.","modified":"2026-10-25T02:47:29.861920635Z","published":"2026-10-23T12:22:08.328Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/99xxx/CVE-2026-99044.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1402fc67d2f4e2e1fc7bf8ee0825b8ad994557ff"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7c1344df1ae0579f57b97647e5203b06496ce10c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b98eb58ba2f8fe8e9bba1b8a3b94fa5602c6de84"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ca8a6285b11d01e5a279b1aa7fb55b1a02ecebb1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/99xxx/CVE-2026-99044.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-99044"},{"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":"eda69d654c7edae21312f731e0308941cb2ee2a9"},{"fixed":"7c1344df1ae0579f57b97647e5203b06496ce10c"},{"fixed":"ca8a6285b11d01e5a279b1aa7fb55b1a02ecebb1"},{"fixed":"b98eb58ba2f8fe8e9bba1b8a3b94fa5602c6de84"},{"fixed":"1402fc67d2f4e2e1fc7bf8ee0825b8ad994557ff"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-99044.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.12.0"},{"fixed":"6.12.114"}]},{"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-2026-99044.json"}}],"schema_version":"1.9.2"}
