CVE-2023-52649
In the Linux kernel, the following vulnerability has been resolved: drm/vkms: Avoid reading beyond LUT array When the floor LUT index (drm_fixp2int(lut_index) is the last index of the array the ceil LUT index will point to an entry beyond the array.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In the Linux kernel, the following vulnerability has been resolved: drm/vkms: Avoid reading beyond LUT array When the floor LUT index (drm_fixp2int(lut_index) is the last index of the array the ceil LUT index will point to an entry beyond the array. Make sure we guard against it and use the value of the floor LUT index. v3: - Drop bits from commit description that didn't contribute anything of value
