Echo: linux: security update to 6.12.30-1

medium Tenable Cloud Security Plugin ID 463769

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: net: mctp: Don't access ifa_index when
 missing In mctp_dump_addrinfo, ifa_index can be used to filter interfaces, but only when the struct
 ifaddrmsg is provided. Otherwise it will be comparing to uninitialised memory - reproducible in the
 syzkaller case from dhcpd, or busybox "ip addr show". The kernel MCTP implementation has always filtered
 by ifa_index, so existing userspace programs expecting to dump MCTP addresses must already be passing a
 valid ifa_index value (either 0 or a real index). BUG: KMSAN: uninit-value in
