A vulnerability in the Linux kernel's cxl/mbox component allowed unbounded allocation of mailbox output buffers, potentially causing large memory allocations that could trigger kernel warnings, tainting, or panics when panic_on_warn=1 is set. The issue was fixed by clamping the output allocation size to the mailbox payload size, preventing excessive memory allocation.
