{"id":"CVE-2025-68737","summary":"arm64/pageattr: Propagate return value from __change_memory_common","details":"In the Linux kernel, the following vulnerability has been resolved:\n\narm64/pageattr: Propagate return value from __change_memory_common\n\nThe rodata=on security measure requires that any code path which does\nvmalloc -\u003e set_memory_ro/set_memory_rox must protect the linear map alias\ntoo. Therefore, if such a call fails, we must abort set_memory_* and caller\nmust take appropriate action; currently we are suppressing the error, and\nthere is a real chance of such an error arising post commit a166563e7ec3\n(\"arm64: mm: support large block mapping when rodata=full\"). Therefore,\npropagate any error to the caller.","modified":"2026-04-02T13:03:44.916904Z","published":"2025-12-24T12:09:35.773Z","related":["openSUSE-SU-2026:10039-1","openSUSE-SU-2026:10301-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68737.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3e2fc1e57a5361633a4bf4222640c6bfe41ff8ea"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e5efd56fa157d2e7d789949d1d64eccbac18a897"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68737.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68737"},{"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":"a166563e7ec375b38a0fd3a58f7b77e50a6bc6a8"},{"fixed":"3e2fc1e57a5361633a4bf4222640c6bfe41ff8ea"},{"fixed":"e5efd56fa157d2e7d789949d1d64eccbac18a897"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68737.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.18.0"},{"fixed":"6.18.2"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68737.json"}}],"schema_version":"1.7.5"}
