CVE-2026-80736

A flaw was found in the Linux kernel's Thunderbolt driver. The tbconsumeddpbandwidth function attempts to access an array beyond its allocated memory, specifically when handling bandwidth group IDs. This out-of-bounds read can lead to an incorrect calculation of reserved bandwidth for Thunderbolt...

CVE-2026-89931

A flaw was found in the Kernel-based Virtual Machine KVM nVMX component of the Linux kernel. This vulnerability arises from improper handling of nested virtual machine VM exits, where a specific request flag is not consistently cleared.
