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: inet_diag: fix kernel-infoleak for UDP
 sockets KMSAN reported a kernel-infoleak [1], that can exploited by unpriv users. After analysis it turned
 out UDP was not initializing r->idiag_expires. Other users of inet_sk_diag_fill() might make the same
 mistake in the future, so fix this in inet_sk_diag_fill(). [1] BUG: KMSAN: kernel-infoleak in
