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: erspan: make sure erspan_base_hdr is
 present in skb->head syzbot reported a problem in ip6erspan_rcv() [1] Issue is that ip6erspan_rcv() (and
 erspan_rcv()) no longer make sure erspan_base_hdr is present in skb linear part (skb->head) before getting
 @ver field from it. Add the missing pskb_may_pull() calls. v2: Reload iph pointer in erspan_rcv() after
 pskb_may_pull() because skb->head might have changed. [1] BUG: KMSAN: uninit-value in pskb_may_pull_reason
