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: ipv4: ip_gre: make ipgre_header()
 robust Analog to commit db5b4e39c4e6 ("ip6_gre: make ip6gre_header() robust") Over the years, syzbot found
 many ways to crash the kernel in ipgre_header() [1]. This involves team or bonding drivers ability to
 dynamically change their dev->needed_headroom and/or dev->hard_header_len In this particular crash
 mld_newpack() allocated an skb with a too small reserve/headroom, and by the time mld_sendpack() was
 called, syzbot managed to attach an ipgre device. [1] skbuff: skb_under_panic: text:ffffffff89ea3cb7
