Memory corruption via freed buffer access
Published Nov 4, 2024 · Updated Nov 8, 2024
Use-after-free in Qualcomm Snapdragon ComputerVision allows local users with high privileges to corrupt memory through buffer-unmapping IOCTLs. The component frees a buffer during an unmap IOCTL and subsequently accesses that released memory, although Qualcomm has not disclosed the affected function or lifetime sequence. Exploitation requires local high-privileged access and no user interaction; CISA reports no public exploitation.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
