NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-uek-debug package and not the kernel-uek-debug package as distributed by Oracle.
See How to fix? for Oracle:5 relevant fixed versions and status.
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.
