1) Problem Description and Brief Discussion
This updated openSUSE 11.3 kernel fixes the following security bugs:
CVE-2010-3310: local users could corrupt kernel heap memory via ROSE sockets.
CVE-2010-2962: local users could write to any kernel memory location via the i915 GEM ioctl interface. Exploitability requires the presence of a i915 compatible graphics card.
Additionally the update restores the compat_alloc_userspace() inline function and includes several other bug fixes.
Hi! I did set up a PC with i915 graphic chipset 00:02.0 VGA compatible controller: Intel Corporation 82915G/GV/910GL Integrated Graphics Controller (rev 04) 00:02.1 Display controller: Intel Corporation 82915G Integrated Graphics Controller (rev 04) an openSUSE 11.3 x86/ 32Bit running the kernel 2.6.34-7-desktop. I did apply all updates including this Kernel-Update 2.6.34-12-desktop. Now when I try to log on KDE4 the KDE splash screen appears and the system freezes (no reaction on keyboard, mouse or ACPI "on/ off" button). Ĺoging on to IceWM e.g. still works. Rolling back to the 2.6.34-7-desktop does help. Any tips what to do? Try other kernel "flavor"? Is it a bug?! Regards, David. -- Eat, sleep and go running, ;-) David Hücking. Encrypted eMail welcome!

Do you have desktop effects enabled in systemsettings? -- Stefan Seyfried "Any ideas, John?" "Well, surrounding them's out." -- To unsubscribe, e-mail: opensuse-security+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-security+help@opensuse.org

As I installed the openSUSE 11.3 KDE default they are enabled. e.g. pushing the mouse cursor into the top left screen corner showing all windows minimized etc. -- Eat, sleep and go running, ;-) David Hücking.

Disable them. Or add the X11:XOrg repository and do a "zypper dup" from that repository. And then still disable them. I have not been able to get anything intel, neither old nor new, to work reliably on 11.3 original drivers with 3D effects enabled. Without 3D effects, it is better but still not stable. With X11:XOrg drivers it is stable on new intel hardware, but 3D is still hanging the KDE desktop sometimes. -- Stefan Seyfried "Any ideas, John?"

Hello Stefan, I will try that as I get access to the PC again today (it's serving as a MP3 player and more in my favority pub...) Best regards, David. -- Eat, sleep and go running, ;-) David Hücking.
