What to Know

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

wifi: mt76: mt7915: avoid nss underflow in mt7915_mcu_get_sta_nss

If a peer's VHT/HE MCS map has no supported spatial stream (all fields

0x3), the loop exits with nss == 0 and the function returned (u8)-1 (255),

which was then written into the firmware sta_rec_bf beamforming fields.

Clamp the result to 0. (NVD)

What to Do

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