UBUNTU-CVE-2021-47305

In the Linux kernel, the following vulnerability has been resolved: dma-buf/syncfile: Don't leak fences on merge failure Each addfence call does a dmafenceget on the relevant fence. In the error path, we weren't calling dmafenceput so all those fences got leaked. Also, in the kreallocarray failur...

kernel: drm/i915: mark requests for GuC virtual engines to avoid use-after-free

A use-after-free vulnerability was found in the Linux kernel Intel i915 graphics driver's GuC virtual engine request handling. A local user with access to GPU rendering can create requests on GuC virtual engines and trap references via syncfile or dmabuf, causing fence release operations to acces...
