CVE-2016-3707: The icmp_check_sysrq function in net/ipv4/icmp.c in the kernel.org projects/rt patches for the Linux kernel...

Security readout for executives and security teams

CVE-2016-3707 affects certain Linux real-time kernel builds. A remote attacker may be able to trigger Linux SysRq actions through crafted ICMP Echo Requests, potentially causing disruptive kernel-level operations. Exposure appears limited to real-time kernel variants using the affected rt patches, not ordinary Linux deployments by default. Most likely exposed assets are RHEL for Real Time 7 systems with vulnerable kernel-rt packages and other vendor real-time kernels covered by Red Hat or SUSE advisories. Internet or untrusted-network ICMP reachability increases concern, but the bundle does not provide a complete affected product list. Prioritize remediation for real-time Linux hosts that are reachable from untrusted networks or support critical operations. The issue is old and not KEV-listed, but the potential impact is operationally serious because SysRq actions can affect kernel behavior. Mitigation focus: Apply the relevant Red Hat or SUSE kernel-rt security updates.; Prioritize externally reachable real-time Linux systems first.; Restrict unnecessary ICMP Echo Request exposure at trust boundaries..
