Key Details

Affected Products, Subsystems & Sectors

What to Know

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

wifi: rsi: avoid reading TKIP MIC keys for non-TKIP ciphers

rsi_hal_load_key() copies tx_mic_key and rx_mic_key from data[16] and

data[24] whenever key data is present. Those offsets are only part of

the 32-byte TKIP key layout. Shorter keys used by other ciphers, such as

CCMP, do not provide those bytes, so the unconditional copies can read

past the supplied key buffer.

Only copy the MIC keys for TKIP, and reject malformed TKIP keys that are

shorter than the expected 32-byte layout.
