Description

In the Linux kernel, the following vulnerability has been resolved: video: screen_info: Relocate framebuffers behind PCI bridges Apply PCI host-bridge window offsets to screen_info framebuffers. Fixes invalid access to I/O memory. Resources behind a PCI host bridge can be relocated by a certain offset in the kernel's CPU address range used for I/O. The framebuffer memory range stored in screen_info refers to the CPU addresses as seen during boot (where the offset is 0). During boot up, firmwa…
