SUSE CVE-2024-31145

Certain PCI devices in a system might be assigned Reserved Memory Regions specified via Reserved Memory Region Reporting, "RMRR" for Intel VT-d or Unity Mapping ranges for AMD-Vi. These are typically used for platform tasks such as legacy USB emulation. Since the precise purpose of these regions ...

AZL-49105 CVE-2024-42259 affecting package kernel for versions less than 5.15.167.1-1

In the Linux kernel, the following vulnerability has been resolved: drm/i915/gem: Fix Virtual Memory mapping boundaries calculation Calculating the size of the mapped area as the lesser value between the requested size and the actual size does not consider the partial mapping offset. This can cau...

CVE-2024-42259

The CVE-2024-42259 issue affects the Linux kernel DRM/i915 gem memory mapper. The root cause was a miscalculation of the mapped region size when a partial mapping offset is involved, which could permit a page fault on access. The fix changes how the mapping boundaries are computed: the start and ...
