CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's amdgpu driver, specifically in the handling of the VFCT ACPI table, which is not properly released after being fetched. This oversight can lead to resource leaks, potentially impacting system stability and performance. Organizations utilizing Linux systems with AMD graphics hardware should prioritize addressing this issue to ensure optimal operation and prevent potential degradation of service.
Original NVD 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)
