Summary

linux, linux-aws, linux-azure, linux-gcp, linux-hwe-5.8, linux-kvm, linux-oem-5.6, linux-oracle, linux-raspi vulnerability

Details

Alexander Popov discovered that multiple race conditions existed in the AF_VSOCK implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code.
