Privilege escalation via unrestricted IPA IOCTL access
Published Nov 22, 2024 · Updated Nov 22, 2024
Privilege escalation in Qualcomm Snapdragon IPA firmware allows local users to gain elevated access by issuing restricted IOCTL calls. The IPA driver exposes IOCTL operations to unprivileged processes instead of enforcing the intended access restrictions. Qualcomm's published assessment requires high privileges, while public materials omit the affected IOCTL names and resulting operation details.

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.
