Description OSIDB Bzimport 2025-10-22 14:06:59 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ACPI: x86: s2idle: Catch multiple ACPI_TYPE_PACKAGE objects

If a badly constructed firmware includes multiple `ACPI_TYPE_PACKAGE`
objects while evaluating the AMD LPS0 _DSM, there will be a memory
leak.  Explicitly guard against this.
