The hif2\ncall also re-enabled hwrro_mode, which the failed primary attach had\njust turned off.\n\nSkip the hif2 WED setup when the primary WED device is not active.","modified":"2026-09-19T03:47:25.990657763Z","published":"2026-09-17T16:08:58.905Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90351.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/76144da3c6184c7850631ad79d0600ac8bf7649a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7c1924332e986019c6bcddf55c843361cccac73f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d566387df8306257d2f703a0d99fd9896400317e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90351.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90351"},{"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":"83eafc9251d6d30574b629ac637c56d168fcbdd9"},{"fixed":"76144da3c6184c7850631ad79d0600ac8bf7649a"},{"fixed":"d566387df8306257d2f703a0d99fd9896400317e"},{"fixed":"7c1924332e986019c6bcddf55c843361cccac73f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90351.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.8.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90351.json"}}],"schema_version":"1.9.0"}
