CVE-2020-24394  (opens in a new tab)
CWE-732  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 5.7.8 or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure. In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered.
