Qualcomm Multiple Chipsets Use-After-Free Vulnerability

Qualcomm · Multiple Chipsets

Summary

A use-after-free flaw in Qualcomm's multiple chipsets, affecting Snapdragon Auto, Compute, Connectivity, Consumer IoT, Industrial IoT, Mobile, and Voice & Music platforms, occurs when process shell memory is freed via an IOCTL munmap call while process initialization is still in progress. An attacker with local access and low privileges, requiring no user interaction, could trigger the condition to compromise the confidentiality, integrity, and availability of the affected system.

Official description · NVD

Possible use after free when process shell memory is freed using IOCTL munmap call and process initialization is in progress in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music
