CVE-2026-11985 Cross-thread FPU register leak on ARM when FPU enabled without register sharing

On the Zephyr ARM port, enabling the hardware FPU CONFIGFPU forces the "Floating point ABI" choice, which defaults to CONFIGFPHARDABI. Both FPHARDABI and FPSOFTABI permit the compiler to emit hardware FP instructions in any function, even code that never uses floating-point types. However, the...

CVE-2026-11985

CVE-2026-11985 describes a cross-thread information leak on the Zephyr ARM port when the hardware FPU is enabled (CONFIG_FPU) but FPU register sharing is disabled. With default FP_ABI (FP_HARDABI) or FP_SOFTABI, FP instructions can be emitted in any function, while callee-saved FP registers (s16-...
