CVE-2026-46290

The CVE describes a Linux kernel issue in x86/efi: after FPU-related softirq changes, kernel_fpu_begin() uses fpregs_lock() with local_bh_disable(), setting SOFTIRQ_OFFSET during EFI runtime calls. This makes in_interrupt() return true in normal task context, causing efi_crash_gracefully_on_page_...
