kernel: blk-mq: avoid double ->queue_rq() because of early timeout

In the Linux kernel, the following vulnerability has been resolved: blk-mq: avoid double -queuerq because of early timeout David Jeffery found one double -queuerq issue, so far it can be triggered in VM use case because of long vmexit latency or preempt latency of vCPU pthread or long page fault ...

kernel: TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED leading to guest malfunctioning

A flaw was found in the x86 KVM subsystem in kvmstealtimesetpreempted in arch/x86/kvm/x86.c in the Linux kernel. Unprivileged guest users can compromise the guest kernel because TLB flush operations are mishandled in certain KVMVCPUPREEMPTED situations...

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 ...
