kernel: Linux kernel: vsock vulnerability may lead to memory corruption

A flaw was found in the Linux kernel's vsock component. This vulnerability occurs when a connect operation on an already established socket is interrupted by a signal or timeout, causing the system to mishandle the socket's state. This incorrect handling can lead to a race condition, potentially...

kernel: net: atlantic: fix fragment overflow handling in RX path

An out-of-bounds write vulnerability was found in the Aquantia Atlantic network driver in the Linux kernel. When receiving packets that span more than MAXSKBFRAGS 17 fragments, the driver writes beyond the skb fragment array bounds in skbaddrxfrag, causing kernel memory corruption and panic...

CVE-2026-23095

In the Linux kernel, the following vulnerability has been resolved: gue: Fix skb memleak with inner IP protocol 0. syzbot reported skb memleak below. 0 The repro generated a GUE packet with its inner protocol 0. gueudprecv returns -guehdr-protoctype for "resubmit" in ipprotocoldeliverrcu, but thi...

CVE-2026-23057

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: Coalesce only linear skb vsock/virtio common tries to coalesce buffers in rx queue: if a linear skb with a spare tail room is followed by a small skb length limited by GOODCOPYLEN = 128, an attempt is made to join...

CVE-2026-23069

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: fix potential underflow in virtiotransportgetcredit The credit calculation in virtiotransportgetcredit uses unsigned arithmetic: ret = vvs-peerbufalloc - vvs-txcnt - vvs-peerfwdcnt; If the peer shrinks its advertise...

UBUNTU-CVE-2026-23083

In the Linux kernel, the following vulnerability has been resolved: fou: Don't allow 0 for FOUATTRIPPROTO. fouudprecv has the same problem mentioned in the previous patch. If FOUATTRIPPROTO is set to 0, skb is not freed by fouudprecv nor "resubmit"-ted in ipprotocoldeliverrcu. Let's forbid 0 for...

UBUNTU-CVE-2026-23048

In the Linux kernel, the following vulnerability has been resolved: udp: call skborphan before skbattemptdeferfree Standard UDP receive path does not use skb-destructor. But skmsg layer does use it, since it calls skbsetownersksafe from udpreadskb. This then triggers this warning in...

CVE-2026-23086 vsock/virtio: cap TX credit to local buffer size

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: cap TX credit to local buffer size The virtio transports derives its TX credit directly from peerbufalloc, which is set from the remote endpoint's SOVMSOCKETSBUFFERSIZE value. On the host side this means that the...
