AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a memory leak in the Linux kernel's radeon driver. Specifically, when the radeon driver reads BIOS information from the ACPI table in the function radeon_acpi_vfct_bios(), it fails to call acpi_put_table() to release the ACPI memory after initialization. This missing call causes a memory leak, which was fixed by adding the proper acpi_put_table() call.
How can this vulnerability impact me? :
The vulnerability causes a memory leak in the Linux kernel when using the radeon driver. Over time, this could lead to increased memory usage and potentially degrade system performance or stability due to unreleased ACPI memory resources.
