Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.8.3
Description
The issue allows local users to cause a denial of service, resulting in stack memory corruption and panic, by reading the /proc/keys file. This occurs due to the
proc keys show function using an incorrect buffer size for certain timeout data when the GNU Compiler Collection (gcc) stack protector is enabled.Recommendations
For Linux kernel versions prior to 4.8.3, update to version 4.8.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the /proc/keys file to minimize the risk of exploitation.
