GFP_KERNEL allocations here, both\nthe local kzalloc_obj() and the ones inside kobject_uevent_env() itself,\ncan trigger reclaim that waits on that blocked I/O and deadlock.\n\nUse memalloc_noio_save()/restore() to cover the whole call instead of\njust the local allocation.","modified":"2026-08-18T03:31:13.002134200Z","published":"2026-08-15T12:27:42.965Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74526.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/ccff8c92571500fcfed21281e33daaf645bf692f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/df817b19dac7034416d18f14347010b3e9f5cf3d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74526.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74526"},{"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":"ec54b348f274fdd2bd32bbe74de6d62ae1a10a18"},{"fixed":"df817b19dac7034416d18f14347010b3e9f5cf3d"},{"fixed":"ccff8c92571500fcfed21281e33daaf645bf692f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74526.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.1.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74526.json"}}],"schema_version":"1.9.0"}
