High

VectorAV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An issue exists in the libceph component of the Linux kernel where errors from ceph auth handle reply done() are not correctly returned from the mon handle auth done() function. This can lead to higher layers incorrectly interpreting authentication status, while background session establishment attempts continue. In secure mode, this may result in a warning in the setup crypto() function and a subsequent NULL pointer dereference within the prepare auth signature() function.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
