Local driver IOCTL bug reachable by an unprivileged on-device app (AV:L, PR:L) with no user interaction, and kernel memory corruption yields full CIA impact within an unchanged scope.

Memory Corruption when processing multiple IOCTL calls with the same buffer file descriptor input due to accessing already freed memory.
AnalysisAI
Use-after-free memory corruption in Qualcomm Snapdragon platform driver code allows a local low-privileged process to trigger access of already-freed memory by issuing multiple IOCTL calls that reference the same buffer file descriptor. A successful attacker gains full compromise of confidentiality, integrity, and availability on the affected device, which in practice can mean kernel-level code execution or privilege escalation from an unprivileged app. There is no public exploit identified at time of analysis, EPSS is negligible (0.09%, 1st percentile), and CISA SSVC records no known exploitation.
