{"id":"CVE-2026-98249","summary":"arm64: hibernate: pass HVC_SET_VECTORS args to the resume hvc","details":"In the Linux kernel, the following vulnerability has been resolved:\n\narm64: hibernate: pass HVC_SET_VECTORS args to the resume hvc\n\nswsusp_arch_suspend_exit() reinstalls the restored kernel's hyp stub\nvectors with an hvc, but never passes the arguments. x0 is not set to\nHVC_SET_VECTORS and x1 is not set to the vector address, so the stub\ndispatch falls through and returns without writing vbar_el2. EL2 is\nleft pointing at the trans_pgd copy of the vectors, a page that\nswsusp_free() releases right after resume.\n\nSet the arguments up the same way __hyp_set_vectors() does.\n\nWithout this fix, Vladimir was able to trigger a hang when resuming from\nhibernation with CONFIG_PAGE_POISONING=y and page_poison=on.","modified":"2026-10-08T02:52:55.086495183Z","published":"2026-10-06T08:45:17.414Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98249.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/60a3c319f1127c4d247d4ed235c5d65376d5e745"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6646418d1032cac25110526161f60d255ed08397"},{"type":"WEB","url":"https://git.kernel.org/stable/c/909e92423db7299e0206232051aa21fe129f65d0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/955d86e5f3b95b731991fdb84966c50b16314629"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d3f8f773312af69eaf4dda106d76d6d42e4362e5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e80ea8118a073a30ebe7a31bd78938c2b1751acc"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98249.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98249"},{"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":"788bfdd97434982b6d575062581e8e72eea755af"},{"fixed":"6646418d1032cac25110526161f60d255ed08397"},{"fixed":"909e92423db7299e0206232051aa21fe129f65d0"},{"fixed":"60a3c319f1127c4d247d4ed235c5d65376d5e745"},{"fixed":"e80ea8118a073a30ebe7a31bd78938c2b1751acc"},{"fixed":"d3f8f773312af69eaf4dda106d76d6d42e4362e5"},{"fixed":"955d86e5f3b95b731991fdb84966c50b16314629"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98249.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.54"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98249.json"}}],"schema_version":"1.9.0"}
