CVE-2026-23114

Summary (CVE-2026-23114) The Linux kernel arm64 FPSIMD/SVE state management vulnerability arises when SVE is supported but SME is not: a ptrace write to the NT_ARM_SVE regset can place the tracee in an invalid state, storing non-streaming SVE data in FP_STATE_SVE format while TIF_SVE is not set. ...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from improper handling of SVE writes by ptrace in the arm64/fpsimd architecture. This vulnerability may lead...
