- Summary
- [none]
- Details
-
The mm subsystem in the Linux kernel through 3.2 does not properly enforce the CONFIGSTRICTDEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c.
