Description Mark J. Cox 2006-01-06 16:47:49 UTC
CVE-2006-0095 says:
        dm-crypt in Linux kernel 2.6.15 and earlier does not clear a
        structure before it is freed, which leads to a memory
        disclosure that could allow local users to obtain sensitive
        information about a cryptographic key.

More details and the straightforward patch are here:
