Vendor: Qualcomm

Description

The vulnerability allows a malicious application to escalate privileges on the system.

The vulnerability exists due to insufficient validation of user-supplied input in NR5G within the Modem component. A malicious application can trigger a heap-based buffer overflow and execute arbitrary code with elevated privileges.

Mitigation
Install updates from vendor's website.
