CVE-2016-7042: Linux Kernel

Medium severity, CVSS 6.2. EPSS: 0.4% chance of exploitation in the next 30 days.

The proc_keys_show function in security/keys/proc.c in the Linux kernel through 4.8.2, when the GNU Compiler Collection (gcc) stack protector is enabled, uses an incorrect buffer size for certain timeout data, which allows local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file.

Affected products

• Linux Linux Kernel: up to and including 4.8.2
