CVE-2026-74580 vhost: reset the vring metadata cache on vring reconfiguration
In the Linux kernel, the following vulnerability has been resolved: vhost: reset the vring metadata cache on vring reconfiguration vq-metaiotlb caches the vhostiotlbmap that backs each vring metadata region, and iotlbaccessok returns early on a cache hit, taking the hit as proof that the region h...
CVE-2026-74580: Undefined Security Weakness
In the Linux kernel, the following vulnerability has been resolved: vhost: reset the vring metadata cache on vring reconfiguration vq-metaiotlb caches the vhostiotlbmap that backs each vring metadata region, and iotlbaccessok returns early on a cache hit, taking the hit as proof that the region h...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the vhost component where the vring metadata cache vq-meta iotlb is not reset during vring reconfiguration. Specifically, when VHOST SET VRING ADDR replaces vq-desc,...
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...
