Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-986790 advisory.

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

 can: j1939: j1939_send_one(): fix missing CAN header initialization

 The read access to struct canxl_frame::len inside of a j1939 created skbuff revealed a missing initialization of reserved and later filled elements in struct can_frame.

 This patch initializes the 8 byte CAN header with zero.
