Description
In the Linux kernel, the following vulnerability has been resolved:
secretmem: disable memfd_secret() if arch cannot set direct map
Return -ENOSYS from memfd_secret() syscall if !can_set_direct_map(). This
is the case for example on some arm64 configurations, where marking 4k
PTEs in the direct map not present can only be done if the direct map is
set up at 4k granularity in the first place (as ARM's break-before-make
semantics do not easily allow breaking apart large/gigantic pages).
