Local information disclosure via kernel logic error
Published Oct 6, 2026 · Updated Oct 6, 2026
Information disclosure in the Android kernel's hwcrypto-kdn.c allows local users with System privileges to read protected information. The kdn_set_sysregs_prot function contains a logic error, but Google has not disclosed the incorrect operation or the data exposed. Exploitation requires System-level code execution on an affected Android device and no user interaction; the disclosure is local, not network-reachable.
