Recommendation: Monitor — no exploitation signal at the moment.

In PMRChangeSparseMemOSMem of physmem_osmem_linux.c, there is a possible arbitrary code execution due to a use after free. This could lead to local escalation of privilege in the kernel with no additional execution privileges needed. User interaction is not needed for exploitation.
