Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel:

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. (CVE-2009-1337)

The selinux_ip_postroute_iptables_compat function in security/selinux/hooks.c in the SELinux subsystem in the Linux kernel before 2.6.27.22, and 2.6.28.x before 2.6.28.10, when compat_net is enabled, omits calls to avc_has_perm for the (1) node and (2) port, which allows local users to bypass intended restrictions on network traffic. NOTE: this was incorrectly reported as an issue fixed in 2.6.27.21. (CVE-2009-1184)

drivers/char/agp/generic.c in the agp subsystem in the Linux kernel before 2.6.30-rc3 does not zero out pages that may later be available to a user-space process, which allows local users to obtain sensitive information by reading these pages. (CVE-2009-1192)

Integer overflow in rose_sendmsg (sys/net/af_rose.c) in the Linux kernel 2.6.24.4, and other versions before 2.6.30-rc1, might allow remote attackers to obtain sensitive information via a large length value, which causes garbage memory to be sent. (CVE-2009-1265)
