{"id":"CVE-2025-71115","summary":"um: init cpu_tasks[] earlier","details":"In the Linux kernel, the following vulnerability has been resolved:\n\num: init cpu_tasks[] earlier\n\nThis is currently done in uml_finishsetup(), but e.g. with\nKCOV enabled we'll crash because some init code can call\ninto e.g. memparse(), which has coverage annotations, and\nthen the checks in check_kcov_mode() crash because current\nis NULL.\n\nSimply initialize the cpu_tasks[] array statically, which\nfixes the crash. For the later SMP work, it seems to have\nnot really caused any problems yet, but initialize all of\nthe entries anyway.","modified":"2026-03-20T12:46:36.929029Z","published":"2026-01-14T15:06:02.428Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71115.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/7b5d4416964c07c902163822a30a622111172b01"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dbbf6d47130674640cd12a0781a0fb2a575d0e44"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71115.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-71115"},{"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":"2f681ba4b352cdd5658ed2a96062375a12839755"},{"fixed":"dbbf6d47130674640cd12a0781a0fb2a575d0e44"},{"fixed":"7b5d4416964c07c902163822a30a622111172b01"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-71115.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.3"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-71115.json"}}],"schema_version":"1.7.5"}
