Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: vxlan: Fix uninit-value in
 vxlan_vnifilter_dump() KMSAN reported an uninit-value access in vxlan_vnifilter_dump() [1]. If the length
 of the netlink message payload is less than sizeof(struct tunnel_msg), vxlan_vnifilter_dump() accesses
 bytes beyond the message. This can lead to uninit-value access. Fix this by returning an error in such
 situations. [1] BUG: KMSAN: uninit-value in vxlan_vnifilter_dump+0x328/0x920
