CVE-2026-68238
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Release VFCT ACPI table reference amdgpu_acpi_vfct_bios() fetches the VFCT tab
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)
