What it is

In the Linux kernel, the following vulnerability has been resolved:

firmware: arm_ffa: Validate framework notification message layout

Framework notifications carry an indirect message in the shared RX

buffer. Validate the reported offset and size before using them, reject

zero-length payloads, and ensure that any non-header payload starts at

the UUID field rather than in the middle of the message header.

Use the validated offset and size values for both kmemdup() and the UUID

parsing path so malformed firmware data cannot drive an out-of-bounds

read or an oversized allocation.
