kernel: drm/amdgpu: avoid using null object of framebuffer

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: 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 framebuffer...

SUSE CVE-2024-53115

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: avoid nullptrderef in vmwframebuffersurfacecreatehandle The 'vmwuserobjectbuffer' function may return NULL with incorrect inputs. To avoid possible null pointer dereference, add a check whether the 'bo' is NULL in the...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that originates in the vmwframebuffersurfacecreatehandle function in the drm/vmwgfx component that may return NULL when...

kernel: drm/i915/dpt: Make DPT object unshrinkable

In the Linux kernel, the following vulnerability has been resolved: drm/i915/dpt: Make DPT object unshrinkable In some scenarios, the DPT object gets shrunk but the actual framebuffer did not and thus its still there on the DPT's vm-boundlist. Then it tries to rewrite the PTEs via a stale CPU...

kernel: drm/fbdev-dma: Only set smem_start is enable per module option

In the Linux kernel, the following vulnerability has been resolved: drm/fbdev-dma: Only set smemstart is enable per module option Only export struct fbinfo.fix.smemstart if that is required by the user and the memory does not come from vmalloc. Setting struct fbinfo.fix.smemstart breaks systems...

kernel: nouveau: offload fence uevents work to workqueue

In the Linux kernel, the following vulnerability has been resolved: nouveau: offload fence uevents work to workqueue This should break the deadlock between the fctx lock and the irq lock. This offloads the processing off the work from the irq into a workqueue...

kernel: iommu: Don't reserve 0-length IOVA region

A flaw was found in the Linux kernel. When the bootloader/firmware does not set up the framebuffers, the address and size are 0 in the "iommu-addresses" property. If the IOVA region is reserved with a 0 length, it corrupts the IOVA rbtree with an entry that has pfnhi pfnlo. If the intent is to us...
