CVE-2005-3847 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. The handle_stop_signal function in signal.c in Linux kernel 2.6.11 up to other versions before 2.6.13 and 2.6.12.6 allows local users to cause a denial of service (deadlock) by sending a SIGKILL to a real-time threaded process while it is performing a core dump.. EPSS estimates a 0.27% chance of exploitation in the next 30 days.
