MediumMetricsAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.18.0-193.el8
Description
A memory disclosure flaw was found in the Linux kernel's 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, posing a threat to confidentiality.
Recommendations
For Linux kernel versions prior to 4.18.0-193.el8, update to version 4.18.0-193.el8 or later to resolve the issue. As a temporary workaround, consider restricting access to the /proc/sys/kernel/rh features file to minimize the risk of exploitation.
