Upgrade Minimos:latest linux-virt to version 6.12.17-r0 or higher.

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:

can: ctucanfd: handle skb allocation failure

If skb allocation fails, the pointer to struct can_frame is NULL. This is actually handled everywhere inside ctucan_err_interrupt() except for the only place.

Add the missed NULL check.

Found by Linux Verification Center (linuxtesting.org) with SVACE static analysis tool.
