CVE-2026-52985

   
Software afectado LINUX KERNEL
 
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.
