In the Linux kernel, the following vulnerability has been resolved:
uprobes: fix kernel info leak via "[uprobes]" vma
xoladdvma() maps the uninitialized page allocated by _createxolarea() into userspace. On some architectures (x86) this memory is readable even without VMREAD, VMEXEC results in the same pgprott as VMEXEC|VMREAD, although this doesn't really matter, debugger can read this memory anyway.
