The vulnerability of the kvm_page_track_cleanup() function in the arch/x86/kvm/mmu/pageTrack.c module of the virtualization subsystem on the Linux kernel-based x86 platform allows a attacker to cause a service failure.

The vulnerability of the kvmpagetrackcleanup function in the arch/x86/kvm/mmu/pageTrack.c module of the virtualization subsystem on the Linux kernel-based x86 platform is related to the dereferencing of the NULL pointer. Exploiting this vulnerability could allow an attacker to cause a service...

CVE-2021-47407

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Handle SRCU initialization failure during page track init Check the return of initsrcustruct, which can fail due to OOM, when initializing the page track mechanism. Lack of checking leads to a NULL pointer deref found b...

CVE-2021-47407

The CVE-2021-47407 issue is in the Linux kernel's KVM x86 code related to SRCU initialization during page track setup. The root cause is a missing validation of init_srcu_struct()’s return value, which can fail (e.g., due to OOM) and lead to a NULL pointer dereference found by a modified syzkalle...
