EUVD-2026-25436
In the Linux kernel, the following vulnerability has been resolved:

crash_dump: don't log dm-crypt key bytes in read_key_from_user_keying

When debug logging is enabled, read_key_from_user_keying() logs the first
8 bytes of the key payload and partially exposes the dm-crypt key.  Stop
logging any key bytes.
