CVE-2026-23107

CVE-2026-23107 describes a Linux kernel issue in arm64/fpsimd where restoring a ZA (Streaming/SME) context could leave sve_state NULL if allocated late, causing a NULL pointer dereference when the kernel stores register state if TIF_SME is set. The root cause is that restore_za_context() failed t...
