CVE-2021-1985

TITLE

plural Qualcomm Product out-of-bounds read vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2021-013812

DESCRIPTION

Possible buffer over read due to lack of data length check in QVR Service configuration in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Wearables. plural Qualcomm The product contains an out-of-bounds read vulnerability.Information is obtained and service operation is interrupted (DoS) It may be in a state. The Qualcomm chip is a chip from Qualcomm Corporation of the United States. A way of miniaturizing circuits (mainly semiconductor devices, but also passive components, etc.) and often fabricated on the surface of a semiconductor wafer. A buffer overflow vulnerability exists in several Qualcomm Snapdragon products. The vulnerability stems from the fact that the QVR Service configuration in the program does not properly verify the incoming buffer length, and attackers can exploit this vulnerability to cause excessive reading of the buffer
