{"id":"CVE-2026-90428","summary":"iommu/tegra241-cmdqv: Don't run the error ISR before probe sets up vintfs","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niommu/tegra241-cmdqv: Don't run the error ISR before probe sets up vintfs\n\n__tegra241_cmdqv_probe() requests the error IRQ before it has allocated the\ncmdqv-\u003evintfs array and set cmdqv-\u003enum_vintfs. A CMDQV left enabled with a\nlatched error across a kexec fires the IRQ as soon as it is requested, and\ntegra241_cmdqv_isr() then walks the uninitialized cmdqv-\u003evintfs array.\n\nRequest the IRQ only after cmdqv-\u003evintfs is allocated and zeroed, so that\na latched interrupt firing early runs the ISR against a valid array of NULL\nslots that it safely skips.","modified":"2026-09-18T03:48:38.461364292Z","published":"2026-09-17T16:09:49.783Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90428.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2f627118b668659c6b195ac48beedb1bf8f53368"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5acd67ceb38debe2fbf70ea35e2dec9f7ab01bbd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a168254ff8db08f2292be3d8fcbd37d2bb8c3d2d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b1605a56745f22670205f6561df5771bbbb62a99"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90428.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90428"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"918eb5c856f6ce4cf93b4b38e4b5e156905c5943"},{"fixed":"b1605a56745f22670205f6561df5771bbbb62a99"},{"fixed":"2f627118b668659c6b195ac48beedb1bf8f53368"},{"fixed":"a168254ff8db08f2292be3d8fcbd37d2bb8c3d2d"},{"fixed":"5acd67ceb38debe2fbf70ea35e2dec9f7ab01bbd"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90428.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.12.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"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-2026-90428.json"}}],"schema_version":"1.9.0"}
