CVE-2026-97988

A flaw was found in the Linux kernel's vhost subsystem. When transitioning device address modes or updating feature settings, cached virtual ring pointers and translation metadata are not properly invalidated, leaving stale memory mappings in use. A local attacker with access to the vhost device...

kernel: vhost: reset the vring metadata cache on vring reconfiguration

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...
