Transient service interruption via zero-length MBSSID parsing
Published Oct 7, 2024 · Updated Oct 7, 2024
Buffer over-read in Qualcomm Snapdragon Auto WLAN firmware allows remote attackers to interrupt wireless service via crafted beacon frames. The WLAN host communication parser processes an MBSSID information element with a zero length and reads beyond the element boundary while handling the beacon. No authentication or user interaction is required, but the attacker must transmit a malformed beacon that reaches an affected radio; the documented result is a transient service interruption, not data exposure or code execution.
