GHSA-76P8-35JQ-5X43

Vulnerability from github – Published: 2022-05-02 03:33 – Updated: 2025-04-09 04:11

Details

The kvm_arch_vcpu_ioctl_set_sregs function in the KVM in Linux kernel 2.6 before 2.6.30, when running on x86 systems, does not validate the page table root in a KVM_SET_SREGS call, which allows local users to cause a denial of service (crash or hang) via a crafted cr3 value, which triggers a NULL pointer dereference in the gfn_to_rmap function.
