Summary

CVE-2023-52994: A vulnerability was identified in the Linux kernel that led to a NULL pointer dereference during system suspension when running as a Xen PV guest. This issue occurred due to a missed code path accessing real_mode_header, causing a kernel panic and potentially crashing the system. The vulnerability has been addressed by adding an optional acpi callback allowing the skipping of setting the wakeup address, as this task is handled by the hypervisor in the Xen PV case.
