NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6.18.20-20.229 package and not the kernel-livepatch-6.18.20-20.229 package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

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.
