Official 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.
Technical Analysis
CVE-2026-52985 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
