A stack buffer overflow vulnerability in the Linux kernel's ACPI pfr_update component was resolved. The flaw involved the query_capability() function copying firmware-supplied buffer objects into fixed-size arrays without validating their length, leading to out-of-bounds writes on the stack. This was confirmed by KASAN testing, which showed writes extending beyond the allocated stack frame. The fix introduces length validation before copying, returning an error if buffers are oversized.
