When built as a\nmodule, __initconst causes this data to be freed after module\ninit, but it's later accessed during probe, causing a page fault.\n\nThe imx8mq_vpu_shared_resources is referenced from non-init code,\nso keeping __initconst or __initconst_or_module here is wrong.\n\nDrop the __initconst annotation and let it live in the normal .rodata\nsection.\n\nA bug of __initconst called from regular non-init probe code\nleading to bugs during probe deferrals or during unbind-bind cycles.","modified":"2026-07-08T08:12:26.628174940Z","published":"2026-04-24T14:35:51.421Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31573.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1e7e9119cf9b0d8585b27653b1a6dc31397c252e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e8d97c270cb46a2a88739019d0f8547adc7d97da"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31573.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31573"},{"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":"286d629d10640bc22f3bf46aa4f356eb7975e862"},{"fixed":"1e7e9119cf9b0d8585b27653b1a6dc31397c252e"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e0203ddf9af7c8e170e1e99ce83b4dc07f0cd765"},{"fixed":"e8d97c270cb46a2a88739019d0f8547adc7d97da"}]}],"versions":["v6.19.10","v6.19.9","v6.19.8","v6.19.7","v6.19.6"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-31573.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.19.6"},{"fixed":"6.19.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-31573.json"}}],"schema_version":"1.7.5"}
