CVE-2009-1337

UnknownEPSS 1.26%

Last modified

CVE-2009-1337 is a vulnerability of currently unknown severity. The exit_notify function in kernel/exit.c in the Linux kernel before 2.6.30-rc1 does not restrict exit signals when the CAP_KILL capability is held, which allows local users to send an arbitrary signal to a process by running a program that modifies the exit_signal field and then uses an exec system call to launch a setuid application.. EPSS estimates a 1.26% chance of exploitation in the next 30 days.
