The log_prefix function in kernel/printk.c in the Linux kernel 3.x before 3.4.33 does not properly remove a prefix string from a syslog header, which allows local users to cause a denial of service (buffer overflow and system crash) by leveraging /dev/kmsg write access and triggering a call_console_drivers function call.

Security readout for executives and security teams

CVE-2013-1772 is a Linux kernel denial-of-service flaw. A local user with write access to /dev/kmsg could trigger a kernel logging bug and crash the system. The business impact is availability loss, not confirmed data theft or remote compromise in the provided sources. Exposure is most likely on legacy Linux 3.x systems running kernels earlier than 3.4.33, especially where local users or services can write to /dev/kmsg. Current supported distributions are less likely affected if vendor kernel updates were applied. Treat this as a legacy availability risk. Prioritize internet-facing or multi-user Linux systems only if they still run affected kernels. For modern patched fleets, this is mainly a verification and decommissioning task. Mitigation focus: Apply a vendor-supported kernel update containing the upstream fix.; Upgrade Linux 3.x kernels earlier than 3.4.33 where still present.; Check distribution advisories for backported fixes before relying on version strings..
