Kernel denial of service via unchecked buffer write
Published Oct 14, 2022 · Updated Aug 3, 2024
Out-of-bounds write in UNISOC camera drivers on Android 10 through 12 allows local users to interrupt the device kernel. The driver writes beyond a camera buffer because it omits a required bounds check; UNISOC has not disclosed the affected function or triggering input. Local access to an affected device is required, and the reported consequence is limited to denial of service in the kernel.
