CVE-2026-74310 vhost/net: complete zerocopy ubufs only once

In the Linux kernel, the following vulnerability has been resolved: vhost/net: complete zerocopy ubufs only once vhost-net initializes one ubufinfo per outstanding zerocopy TX descriptor and hands it to the backend socket. The networking stack may then clone a zerocopy skb before all skb referenc...

CVE-2026-74310 vhost/net: complete zerocopy ubufs only once

In the Linux kernel, the following vulnerability has been resolved: vhost/net: complete zerocopy ubufs only once vhost-net initializes one ubufinfo per outstanding zerocopy TX descriptor and hands it to the backend socket. The networking stack may then clone a zerocopy skb before all skb referenc...

CVE-2026-74310

The CVE affects the Linux kernel vhost/net zerocopy path. The bug arises when vhost_zerocopy_complete() treats every ubuf callback as a completed descriptor, dereferences ubuf->ctx, and updates state while a cloned skb still holds the same ubuf_info refcount. This can allow a backend reset to ...

In the Linux kernel, the following vulnerability has been resolved: net: watchdog: fix refcount tracking races Blamed commit converted the untracked devhold/devput calls in the watchdog code to use the tracked devholdtrack/devputtrack which were later renamed/interfaced to netdevhold and netdevpu...

CVE-2026-74257

CVE-2026-74257 stems from a use-after-free in the Linux kernel sockmap path (udp_bpf_recvmsg) where sk_msg_recvmsg() can touch the same sk_msg when multiple threads race. The mitigation described in connected docs is to serialize sk_msg_recvmsg() by callers, specifically by adding a lock around u...

CVE-2026-74256

The CVE-2026-74256 family affects the Linux kernel’s BPF sockmap path, where bpf_msg_pop_data() bounds checks used 32-bit arithmetic on start/len. An unsigned-to-signed overflow could allow an out-of-range start/len, causing the pop loop to walk past scatterlist end and trigger put_page on an emp...

CVE-2026-72478

The CVE describes a bound-checking fix in Linux kernel ntfs3 (fs/ntfs3) for run_get_highest_vcn(), which previously parsed a packed NTFS mapping-pairs buffer without length bounds and could read past the slab allocation, triggering a KASAN slab-out-of-bounds read on mount. The patch adds a run_bu...
