Local memory disclosure via unchecked SEM input
Published Aug 5, 2022 · Updated Aug 3, 2024
Out-of-bounds read in SEM TA on Samsung Mobile Devices before SMR Aug-2022 Release 1 allows local users to read adjacent memory. SEM TA reads memory before validating supplied input, allowing the read to cross the intended buffer boundary. Exploitation requires local access with high privileges and exposes memory contents without reported modification or service interruption.
