In the Linux kernel, the following vulnerability has been resolved: vhost/net: complete zerocopy ubufs only once vhost-net initializes one ubuf_info… (CVE-2026-74310)CVE-2026-74310 0 A use-after-free vulnerability in the Linux kernel's vhost-net zerocopy implementation was resolved. The issue arises because vhost-net incorrectly completes zerocopy ubufs multiple times when skb references are cloned, leading to dereferencing freed memory. This can cause kernel memory corruption detected by KASAN. The fix ensures that vhost descriptor completion occurs only once per ubuf reference, matching the ownership rules for cloned zerocopy skbs.
