Memory disclosure via out-of-bounds buffer-array read
Published Nov 4, 2025 · Updated Nov 4, 2025
An out-of-bounds read in the Samsung Exynos 1380 NPU driver through July 2025 allows remote attackers to disclose memory contents. The __is_done_for_me function indexes q->bufs[] outside its valid bounds and reads memory beyond the buffer array. Unauthenticated remote reachability is sufficient, and the reported consequence is memory disclosure without data modification or service interruption.
