{"id":"CVE-2024-27406","summary":"lib/Kconfig.debug: TEST_IOV_ITER depends on MMU","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nlib/Kconfig.debug: TEST_IOV_ITER depends on MMU\n\nTrying to run the iov_iter unit test on a nommu system such as the qemu\nkc705-nommu emulation results in a crash.\n\n    KTAP version 1\n    # Subtest: iov_iter\n    # module: kunit_iov_iter\n    1..9\nBUG: failure at mm/nommu.c:318/vmap()!\nKernel panic - not syncing: BUG!\n\nThe test calls vmap() directly, but vmap() is not supported on nommu\nsystems, causing the crash.  TEST_IOV_ITER therefore needs to depend on\nMMU.","modified":"2026-04-02T10:07:57.343168Z","published":"2024-05-17T11:40:28.608Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/27xxx/CVE-2024-27406.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1eb1e984379e2da04361763f66eec90dd75cf63e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9e6e541b97762d5b1143070067f7c68f39a408f8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e6316749d603fe9c4c91f6ec3694e06e4de632a3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/27xxx/CVE-2024-27406.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-27406"},{"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":"2d71340ff1d41a5b9fc1b30ded12d638b2e2ae96"},{"fixed":"e6316749d603fe9c4c91f6ec3694e06e4de632a3"},{"fixed":"9e6e541b97762d5b1143070067f7c68f39a408f8"},{"fixed":"1eb1e984379e2da04361763f66eec90dd75cf63e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-27406.json"}}],"schema_version":"1.7.5"}
