Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 6.11. It stems from improper lifecycle management of the nestedmmus array in KVM arm64 nv; after relocation during VCPUINIT, pointers to the now-freed structure are still used, potentially leading to use-after-free conditions...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.16 contains a security vulnerability. This vulnerability stems from the KVM arm64 nv module, which encounters a race condition with stage 2 teardown when handling nested wp/unmap operations. The module does not check whether pgt is empty, which may lead to null pointer...
