Overview

CVE-2026-68238 is a known-severity vulnerability. It was published on August 10, 2026.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: Release VFCT ACPI table reference

amdgpu_acpi_vfct_bios() fetches the VFCT table with acpi_get_table()

but never releases it. acpi_get_table() takes a reference on the

table (incrementing its validation_count and mapping it on the 0->1

transition); without a paired acpi_put_table() the mapping is leaked

on every call, whether or not a matching VBIOS image is found.

Route all exit paths after the table is acquired through a common

acpi_put_table(). The VBIOS image is copied out with kmemdup() before

the table is released, so it remains valid for the caller.

(cherry picked from commit ca5988682b4cba4cd125a0fa99b2de1239164ae4)
