CVE-2026-53282

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the x86 kexec implementation where the purgatory code provided by kexec-tools attempts to access a return address above the top of the stack during a non-kjump kexec. Because the return address is not pushed to the stack in the non-kjump path, this access can lead to a fault and cause the purgatory code to crash.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
