CVE-2017-7889 (retired)

Priority
Description
The mm subsystem in the Linux kernel through 4.10.10 does not properly
enforce the CONFIG_STRICT_DEVMEM 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.
Ubuntu-Description
Tommi Rantala and Brad Spengler discovered that the memory manager in the
Linux kernel did not properly enforce the CONFIG_STRICT_DEVMEM protection
mechanism. A local attacker with access to /dev/mem could use this to
expose sensitive information or possibly execute arbitrary code.
