CVE-2026-23114

In the Linux kernel, the following vulnerability has been resolved: arm64/fpsimd: ptrace: Fix SVE writes on !SME systems When SVE is supported but SME is not supported, a ptrace write to the NTARMSVE regset can place the tracee into an invalid state where non-streaming SVE register data is stored...

CVE-2025-38169

In the Linux kernel, the following vulnerability has been resolved: arm64/fpsimd: Avoid clobbering kernel FPSIMD state with SMSTOP On system with SME, a thread's kernel FPSIMD state may be erroneously clobbered during a context switch immediately after that state is restored. Systems without SME...

CVE-2025-38169

In the Linux kernel (CVE-2025-38169) on arm64 with SME, a thread context switch could clobber the kernel FPSIMD state when restoring a previous kernel FPSIMD state while the CPU is in streaming SVE mode. The bug occurs if fpsimd_thread_switch() calls fpsimd_load_kernel_state() while streaming SVE...
