UnknownEPSS 0.39%

Last modified

CVE-2009-1338 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
