CVE-2026-74702: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: vhost-scsi: reject feature changes after endpoint vhostscsisetupvqcmds runs from VHOSTSCSISETENDPOINT and allocates each command's protection scatterlist array protsgl according to the acknowledged VIRTIOSCSIFT10PI bit. The comma...

CVE-2026-74580

A flaw was found in the Linux kernel's vhost subsystem. A local attacker could exploit this vulnerability by reconfiguring a virtual ring vring using specific ioctl commands while a device Input/Output Memory Management Unit IOTLB is attached. This improper handling of the vring metadata cache ca...

CVE-2026-74312

A flaw was found in the Linux kernel's vhost/vdpa subsystem. Improper validation of the virtqueue index in the vhostvdpammap and vhostvdpafault functions allows an out-of-range index to be used. This can lead to an out-of-bounds memory access in driver-specific callbacks, potentially causing...

CVE-2026-74310

A flaw was found in the Linux kernel's vhost/net component. This use-after-free vulnerability occurs due to incorrect handling of zerocopy user buffers, where the system may prematurely complete buffer operations while other parts of the system still hold references to the same memory. This can...

CVE-2026-74356

A flaw was found in the Linux kernel's vhost subsystem. An incorrect return value from the vhostgetavailidx function can cause the host to livelock. A malicious guest operating system OS can exploit this by not processing virtqueue entries, leading to the host repeatedly disabling notifications a...

SUSE CVE-2026-6426

A type mismatch vulnerability was found in QEMU's vhost inflight migration VMState handling. The destination buffer size is stored as a uint64t but read by the VMSVBUFFER load path as a signed int32t. On little-endian hosts, a crafted incoming migration state with bit 31 set causes the value to b...
