CVE-2024-21460

Information disclosure via contiguous ASLR relocation

Published Jul 1, 2024 · Updated Aug 1, 2024

Information disclosure in Qualcomm Snapdragon components allows local users to read protected memory-layout information through ASLR. ASLR relocates IMEM and Secure DDR as a single contiguous chunk in the virtual address space, insufficiently randomizing their relative placement. Local execution is required; successful exploitation reveals confidential information without modifying data or interrupting service.
