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-...

kernel: powerpc: local user can read vector registers of other users' processes via a Facility Unavailable exception

A flaw in the Linux kernel on the PowerPC platform, was found where a local user can read vector registers of other user processes via a Facility Unavailable exception. An attacker must start a transaction when the FPU operation begins or there is no leakage. Vector registers will become corrupte...

FreeBSD -- System call kernel data register leak

Problem Description: The callee-save registers are used by kernel and for some of them %r8, %r10, and for non-PTI configurations, %r9 the content is not sanitized before return from syscalls, potentially leaking sensitive information. Impact: Typically an address of some kernel data structure use...
