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: Linux kernel KVM: Denial of Service via incorrect NX bit handling in NPT

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. When KVM uses Nested Page Tables NPT with NX huge page mitigation enabled, it incorrectly handles the No-Execute NX bit in Shadow Page Table Entries SPTE. This improper handling can be triggered by a local attacker...

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: 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 ...
