CVE-2019-14105

Kernel memory overflow via misread CSL field

Published Apr 16, 2020 · Updated Aug 5, 2024

Kernel memory corruption in Qualcomm Snapdragon SDA845, SDM845, and SM8150 allows local users to trigger a memory overflow. The kernel reads the CSL-defined reserved field as uint16 rather than uint32, misinterpreting its four-byte value and overflowing memory. Exploitation requires local low-privileged access to an affected device and can expose or corrupt kernel memory or crash the device.
