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...

The new value is tested for validity by temporarily loading it into the fpc register. This may le...
CVE-2021-47226
In the Linux kernel, the following vulnerability has been resolved: x86/fpu: Invalidate FPU state after a failed XRSTOR from a user buffer Both Intel and AMD consider it to be architecturally valid for XRSTOR to fail with PF but nonetheless change the register state. The actual conditions under...

CVE-2017-15537
The x86/fpu Floating Point Unit subsystem in the Linux kernel before 4.13.5, when a processor supports the xsave feature but not the xsaves feature, does not correctly handle attempts to set reserved bits in the xstate header via the ptrace or rtsigreturn system call, allowing local users to read...
