CVE-2009-1338
Published: Apr 22, 2009
Modified: Aug 7, 2024
PUBLISHED
Description
The kill_something_info function in kernel/signal.c in the Linux kernel before 2.6.28 does not consider PID namespaces when processing signals directed to PID -1, which allows local users to bypass the intended namespace isolation, and send arbitrary signals to all processes in all namespaces, via a kill command.
