Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.10.0-327.22.1

Description The issue allows remote attackers to execute SysRq commands via crafted ICMP Echo Request packets. This can be achieved through a brute-force attack to discover a cookie or by exploiting the vulnerability after reading the local icmp echo sysrq file.

Recommendations For Linux kernel versions prior to 3.10.0-327.22.1, update to version 3.10.0-327.22.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the icmp check sysrq function to minimize the risk of exploitation.
