| Vector | AV:A/AC:L/Au:S/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel related to framebuffer relocation behind PCI bridges. The issue arises because framebuffer memory ranges in
screen info are not updated when PCI host bridges relocate resources, potentially leading to invalid access to I/O memory. The pcibios bus to resource() helper function is involved in the relocation process, aiming to match the I/O-memory resource of the PCI graphics device. The fix involves updating screen info to reflect the relocated framebuffer address.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
