Description OSIDB Bzimport 2025-09-15 15:09:19 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/radeon: Add the missed acpi_put_table() to fix memory leak

When the radeon driver reads the bios information from ACPI
table in radeon_acpi_vfct_bios(), it misses to call acpi_put_table()
to release the ACPI memory after the init, so add acpi_put_table()
properly to fix the memory leak.
