CVE-2021-46908

CVE-2021-46908 affects the Linux kernel BPF verifier: the issue stems from using an incorrect permission flag for mixed signed bounds arithmetic. The fix ensures bypass_spec_v1 is used (instead of allow_ptr_leaks) to align with spectre v1 mitigation requirements. The vulnerability has been resolv...

hw: cpu: arm64: Spectre-BHB

A new cache speculation vulnerability, known as Branch History Injection BHI or Spectre-BHB, was found in hw. Spectre-BHB is similar to Spectre v2, except that malicious code uses the shared branch history stored in the CPU Branch History Buffer, or BHB to influence mispredicted branches within t...

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 ...

kernel: Spectre v2 SMT mitigations problem

It was found that the Linux Kernel still left the victim process exposed to attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The kernel failed to protect applications that attempted to protect against Spectre v2 leaving them open to attack from other processes...
