Memory corruption via unchecked partition-size calculation
Published Feb 2, 2026 · Updated Feb 2, 2026
Integer overflow in Qualcomm Snapdragon automotive firmware allows physically proximate attackers to corrupt memory through oversized partitions. The partition-size calculation processes an oversized value without checks that prevent integer wraparound, causing the resulting size to corrupt memory. The attack requires physical proximity and no prior privileges or user interaction; Qualcomm does not disclose whether corruption enables code execution or only a crash.
