- Summary
- Low: kexec-tools security, bug fix, and enhancement update
- Details
-
The kexec-tools packages contain the /sbin/kexec binary and utilities that together form the user-space component of the kernel's kexec feature. The /sbin/kexec binary facilitates a new kernel to boot using the kernel's kexec feature either on a normal or a panic reboot. The kexec fastboot mechanism allows booting a Linux kernel from the context of an already running kernel.
Security Fix(es):
- kexec-tools: incorrect permissions on kdump dmesg file (CVE-2021-20269)
