CVE-2024-27406
Medium
Description
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.
