CVE-2026-53282

The CVE-2026-53282 issue affects the Linux kernel’s x86/kexec purgatory code used by kexec-tools. The root cause was the purgatory path looking above the top of the stack to locate a return address for a kjump even in non-kjump kexec, which could trigger a fault/crash. A commit fixed the actual k...
