CVE-2026-43363 x86/apic: Disable x2apic on resume if the kernel expects so

In the Linux kernel, the following vulnerability has been resolved: x86/apic: Disable x2apic on resume if the kernel expects so When resuming from s2ram, firmware may re-enable x2apic mode, which may have been disabled by the kernel during boot either because it doesn't support IRQ remapping or f...

CVE-2026-43363

CVE-2026-43363 concerns the Linux kernel x86 APIC subsystem. If, on resume from s2ram (S2/S3 wake), firmware re-enables x2APIC mode after the kernel has booted with x2APIC disabled, the system can run with x2APIC hardware but the kernel uses the xapic interface, leading to hangs. The issue is cau...
