CVE-2024-26908 was assigned to an x86/Xen SMP code change in the Linux kernel that added NULL-pointer checks in smp.c. It was associated with an unchecked return value potentially resulting in a NULL-pointer dereference. The Linux kernel CVE project subsequently rejected the identifier upstream; it must therefore not be treated as an active, confirmed vulnerability.
