https://notcve.org/view.php?id=CVE-2021-20269
A flaw was found in the permissions of a log file created by kexec-tools. This flaw allows a local unprivileged user to read this file and leak kernel internal information from a previous panic. The highest threat from this vulnerability is to confidentiality. This flaw affects kexec-tools shipped by Fedora versions prior to 2.0.21-8 and RHEL versions prior to 2.0.20-47.

https://notcve.org/view.php?id=CVE-2015-0267
The Red Hat module-setup.sh script for kexec-tools, as distributed in the kexec-tools before 2.0.7-19 packages in Red Hat Enterprise Linux, allows local users to write to arbitrary files via a symlink attack on a temporary file. La secuencia de comandos de module-setup.sh de Red Hat para kexec-tools, distribuido en los paquetes kexec-tools anterior a 2.0.7-19 en Red Hat Enterprise Linux, permite a usuarios locales escribir en ficheros arbitrarios a través de un ataque de enlace simbólico sobre un fichero temporal. It was found that the module-setup.sh script provided by kexec-tools created temporary files in an insecure way. A malicious, local user could use this flaw to conduct a symbolic link attack, allowing them to overwrite the contents of arbitrary files. • http://rhn.redhat.com/errata/RHSA-2015-0986.html http://www.securityfocus.com/bid/74622 https://access.redhat.com/security/cve/CVE-2015-0267 https://bugzilla.redhat.com/show_bug.cgi?id=1191575 • CWE-377: Insecure Temporary File •
