What to Know

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 hal_buf without validating the response length. A

response exceeding WCN36XX_HAL_BUF_SIZE causes a heap buffer overflow

with firmware-controlled content.

Add a bounds check on the response length. (NVD)

What to Do

Monitor Linux's web page for any future patch releases.
