This article applies to systems with the
k_smpkernel package installed, please use the appropriate kernel package if you are using a different kernel:
- "Security update for Linux kernel (k_deflt)" (http://sdb.suse.de/en/psdb/html/f54ead2affbc4ca9a638647432f0f01b.html)
- "Security update for Linux kernel (k_athlon)" (http://sdb.suse.de/en/psdb/html/8376e89e202b4ff8a110e46f408dcc3a.html)

rpm -qf /boot/vmlinuz
(CAN-2003-0127). The vulnerability allows a local unprivileged attacker to
rootprivileges by using
combination with automatic kernel module loading on request, also known
As a temporary workaround, it is possible to disable the automatic loading of kernel modules by running the following command as root:
echo /no/such/file >/proc/sys/kernel/modprobe
If you do not use the grub bootloader, you should make sure that the boot blocks are initialized after you have successfully performed this kernel update to ensure that your system will start after a reboot.
rpm -Uvh k_smp.rpm mkinitrd
In case you are using lilo, please make sure that you also execute the command
after installing the update and running
mkinitrdfor the system to remain bootable.
Finally, reboot the system with
shutdown -r now
to load the new kernel (replace "
now" with the appropriate amount of time to allow local users to cleanly log out, for example "
+5" for five minutes.)
