Kernel memory corruption via missing buffer validation
Published Mar 24, 2020 · Updated Aug 4, 2024
Out-of-bounds access in Samsung Android 9 kernel Wi-Fi drivers allows local users to read or overwrite memory on Exynos devices. The drivers fail to validate buffer lengths before processing data associated with the Wi-Fi module, permitting access beyond allocated bounds. Successful exploitation requires local low-privileged access and can expose or corrupt kernel memory, including causing a device crash.
