OESA-2024-2123 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Remove rcu locks from user resources User resource lookups used rcu to avoid two extra atomics. Unfortunately the rcu paths were buggy and it was eas...

SUSE CVE-2024-46683

In the Linux kernel, the following vulnerability has been resolved: drm/xe: prevent UAF around preempt fence The fence lock is part of the queue, therefore in the current design anything locking the fence should then also hold a ref to the queue to prevent the queue from being freed. However,...

SUSE CVE-2024-46694

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: avoid using null object of framebuffer Instead of using state-fb-obj0 directly, get object from framebuffer by calling drmgemfbgetobj and return error code when object is null to avoid using null object of...

SUSE CVE-2024-46709

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Fix prime with external buffers Make sure that for external buffers mapping goes through the dmabuf interface instead of trying to access pages directly. External buffers might not provide direct access to...

CVE-2024-46712

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Disable coherent dumb buffers without 3d Coherent surfaces make only sense if the host renders to them using accelerated apis. Without 3d the entire content of dumb buffers stays in the guest making all of the extra...

CVE-2024-46710

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Prevent unmapping active read buffers The kms paths keep a persistent map active to read and compare the cursor buffer. These maps can race with each other in simple scenario where: a buffer "a" mapped for update b...

CVE-2024-46705

In the Linux kernel, the following vulnerability has been resolved: drm/xe: reset mmio mappings with devm Set our various mmio mappings to NULL. This should make it easier to catch something rogue trying to mess with mmio after device removal. For example, we might unmap everything and then start...
