kernel: possibility of memory disclosure when reading the file /proc/sys/kernel/rh_features

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.

kernel: uninitialized kernel data leak in userspace coredumps

A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an attacker with a local account to crash a trivial program and exfiltrate private kernel data.
