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-2026-23086 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...

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...
