The vulnerability (CWE-125) occurs due to improper bounds checking in firmware handling modem/RF communication across multiple Qualcomm chipsets. An attacker can trigger an out-of-bounds read via crafted 5G/LTE packets, potentially leaking sensitive memory contents or causing denial-of-service. The flaw resides in the baseband firmware’s signal processing stack, where malformed protocol headers bypass length validation.
