[USN-4463-1] Linux kernel vulnerabilities

Severity Low
Affected Packages 72
CVEs 2
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

It was discovered that the bcache subsystem in the Linux kernel did not
properly release a lock in some error conditions. A local attacker could
possibly use this to cause a denial of service. (CVE-2020-12771)

Kyungtae Kim discovered that the USB testing driver in the Linux kernel did
not properly deallocate memory on disconnect events. A physically proximate
attacker could use this to cause a denial of service (memory exhaustion).
(CVE-2020-15393)
