CVE-2009-2287

The kvmarchvcpuioctlsetsregs 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 KVMSETSREGS call, which allows local users to cause a denial of service crash or hang via a crafted cr3 value, which triggers a NULL pointer...

CVE-2009-2287

CVE-2009-2287 affects the Linux kernel’s KVM on x86, where KVM_SET_SREGS does not validate the page-table root (cr3). This can allow a local attacker to crash or hang the host (denial of service) via a crafted cr3 value, triggering a NULL pointer dereference in gfn_to_rmap. The issue is documente...
