QEMU: VNC: integer underflow in vnc_client_cut_text_ext leads to CPU exhaustion

An integer underflow issue was found in the QEMU built-in VNC server while processing ClientCutText messages in the extended format. A malicious client could use this flaw to make QEMU unresponsive by sending a specially crafted payload message, resulting in a denial of service...

kernel: KVM: NULL pointer dereference in kvm_mmu_invpcid_gva

A flaw was found in KVM. With shadow paging enabled if INVPCID is executed with CR0.PG=0, the invlpg callback is not set, and the result is a NULL pointer dereference. This flaw allows a guest user to cause a kernel oops condition on the host, resulting in a denial of service...

kernel: crypto: ccp - Use kzalloc for sev ioctl interfaces to prevent kernel memory leak

In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - Use kzalloc for sev ioctl interfaces to prevent kernel memory leak For some sev ioctl interfaces, input may be passed that is less than or equal to SEVFWBLOBMAXSIZE, but larger than the data that PSP firmware return...

kernel: KVM: nVMX: missing IBPB when exiting from nested guest can lead to Spectre v2 attacks

A flaw was found in the KVM's Intel nested virtualization feature nVMX. Since L1 and L2 shared branch prediction modes guest-user and guest-kernel, KVM did not protect indirect branches in L1 from steering by a malicious agent in L2. This could allow a malicious nested guest to carry out Spectre ...
