[USN-4678-1] Linux kernel vulnerabilities

Severity Medium
Affected Packages 46
CVEs 2
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

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)
