NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-virt package and not the linux-virt package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

ksmbd: validate zero num_subauth before sub_auth is accessed

Access psid->sub_auth[psid->num_subauth - 1] without checking if num_subauth is non-zero leads to an out-of-bounds read. This patch adds a validation step to ensure num_subauth != 0 before sub_auth is accessed.
