Summary

linux, linux-hwe-5.8, linux-aws, linux-azure, linux-gcp, linux-kvm, linux-oracle, linux-raspi vulnerabilities

Details

It was discovered that the AMD Running Average Power Limit (RAPL) driver in the Linux kernel did not properly restrict access to power data. A local attacker could possibly use this to expose sensitive information. (CVE-2020-12912)

Jann Horn discovered that the io_uring subsystem in the Linux kernel did not properly perform reference counting in some situations. A local attacker could use this to expose sensitive information or possibly escalate privileges. (CVE-2020-29534)
