Summary
wifi: wcn36xx: fix heap overflow from oversized firmware HAL response
Details

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

wifi: wcn36xx: fix heap overflow from oversized firmware HAL response

The firmware response dispatcher copies all synchronous HAL responses into the 4096-byte halbuf without validating the response length. A response exceeding WCN36XXHALBUFSIZE causes a heap buffer overflow with firmware-controlled content.

Add a bounds check on the response length.
