Resolved Date: Jul 31, 2026

Found In Version: 10.25.33.2

Severity: Standard

Applicable for: Wind River Linux LTS 25

Component/s: Kernel

Description

In the Linux kernel, the following vulnerability has been resolved:  netdevsim: zero initialize struct iphdr in dummy sk_buff  Syzbot reports a KMSAN uninit-value originating from nsim_dev_trap_skb_build, with the allocation also being performed in the same function.  Fix this by calling skb_put_zero instead of skb_put to guarantee zero initialization of the whole IP header.
