CVE-2025-38585

Kernel stack overwrite via stale EFI status

Published Aug 19, 2025 · Updated Jun 15, 2026

Stack-based buffer overflow in the Linux atomisp camera driver allows local users to corrupt kernel memory during device initialization. gmin_get_config_var() returns a stale success value after EFI_BUFFER_TOO_SMALL enlarges the reported length without filling the 65-byte buffer, so gmin_get_var_int() writes a terminator beyond that buffer. Reachability requires an EFI variable longer than 64 bytes and atomisp camera initialization on an Intel Bay Trail or Cherry Trail platform.
