It was discovered that the NFS implementation in the Linux kernel did not properly prevent access outside of an NFS export that is a subdirectory of a file system.

A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-36158)

A local attacker could use this to ease exploitation of another kernel vulnerability. (CVE-2021-20239)

A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-3347)

An attacker could possibly use this to bypass NFS access restrictions. (CVE-2021-3178)
