CVE-2013-1772

UnknownEPSS 0.38%

Last modified

CVE-2013-1772 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.38% chance of exploitation in the next 30 days.
