CVE-2024-27237

Local memory disclosure via incorrect wipe size

Published Mar 11, 2024 · Updated Mar 25, 2025

Incorrect buffer-size calculation in Google Android 13 allows local users to disclose memory through the Pixel bootloader. The wipe_ns_memory function in nsmemwipe.c uses an incorrectly calculated size while wiping namespace memory, causing the information exposure. Exploitation requires low-privileged local access, needs no user interaction, and has no reported data-modification or service-interruption impact.
