A memory disclosure flaw was found in the Linux kernel's versions before 4.18.0-193.el8 in the sysctl subsystem when reading the /proc/sys/kernel/rh_features file. This flaw allows a local user to read uninitialized values from the kernel memory. The highest threat from this vulnerability is to confidentiality.
The product uses a sequential operation to read or write a buffer, but it uses an incorrect length value that causes it to access memory that is outside of the bounds of the buffer.
