VAR-201705-1958

Vulnerability from variot - Updated: 2025-04-20 23:27

The GPU driver in Huawei P7 phones with software P7-L00 before P7-L00C17B851, P7-L05 before P7-L05C00B851, and P7-L09 before P7-L09C92B851 allows local users to read or write to arbitrary kernel memory locations and consequently cause a denial of service (system crash) or gain privileges via a crafted application. HuaweiP7 is a smartphone from China's Huawei company. GPUdriver is a graphics processor driver used in it. The GPU driver in HuaweiP7 has a privilege escalation vulnerability that stems from the GPU's failure to adequately verify the validity of incoming parameters. A local attacker can use this vulnerability to spoof a user to install a malicious application to read and modify the memory address of the product, causing a system crash or privilege escalation. Huawei P7 is prone to a local privilege-escalation vulnerability. Local attackers may exploit this issue to gain elevated privileges. The following versions are affected: Huawei P7 versions prior to P7-L00C17B851, versions prior to P7-L05C00B851, versions prior to P7-L09C92B851
