SUSE CVE-2026-46234

In the Linux kernel, the following vulnerability has been resolved: vsock: fix buffer size clamping order In vsockupdatebuffersize, the buffer size was being clamped to the maximum first, and then to the minimum. If a user sets a minimum buffer size larger than the maximum, the minimum check...

CVE-2026-46207

A flaw was found in the Linux kernel's vsock/virtio component. When processing non-linear data buffers for the vsockmon tap device, the system did not correctly initialize the payload. This oversight could lead to uninitialized data being copied to the monitoring interface, potentially resulting ...

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-007479 advisory. In the Linux kernel, the following vulnerability has been resolved: vsock: Do not allow binding to VMADDRPORTANY It is possible for a vsock to autobind to...

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...

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...
