{"id":"DEBIAN-CVE-2024-27406","details":"In the Linux kernel, the following vulnerability has been resolved:  lib/Kconfig.debug: TEST_IOV_ITER depends on MMU  Trying to run the iov_iter unit test on a nommu system such as the qemu kc705-nommu emulation results in a crash.      KTAP version 1     # Subtest: iov_iter     # module: kunit_iov_iter     1..9 BUG: failure at mm/nommu.c:318/vmap()! Kernel panic - not syncing: BUG!  The test calls vmap() directly, but vmap() is not supported on nommu systems, causing the crash.  TEST_IOV_ITER therefore needs to depend on MMU.","modified":"2026-09-15T09:03:01.945484097Z","published":"2024-05-17T12:15:10.757Z","upstream":["CVE-2024-27406"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-27406"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.7.7-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-27406.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.7.7-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-27406.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
