CVE-2009-1338

Publication date 22 April 2009

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

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.
