Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw within the libceph component, specifically in the handle auth session key() function. This issue could lead to potential out-of-bounds writes due to insufficient boundary checks on the len field, which originates from untrusted network packets. The lack of proper validation when decrypting connection secrets or processing service tickets could allow for exploitation.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
