The vulnerability of the overlayfs component in the Linux operating system’s kernel allows for insecure privilege management. This enables attackers to gain access to confidential data, compromise its integrity, and cause service failures.

The vulnerability of the overlayfs component in the Linux operating system’s kernel involves ignoring user name spaces when configuring file permissions in the underlying file system. Exploiting this vulnerability allows an attacker to gain access to confidential data, compromise its integrity, a...
