CVE-2026-46147
CVE-2026-46147 concerns the Linux kernel KVM on ARM64, where two bugs in vCPU initialisation can leak pin references to host vCPU/SVE pages and allow observation of a partially initialised vCPU object. The fixes extract a helper for vCPU registration, ensure proper unpinning on error, and enforce...
SUSE CVE-2026-23107
In the Linux kernel, the following vulnerability has been resolved: arm64/fpsimd: signal: Allocate SSVE storage when restoring ZA The code to restore a ZA context doesn't attempt to allocate the task's svestate before setting TIFSME. Consequently, restoring a ZA context can place a task into an...

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...

DEBIAN-CVE-2023-53184
In the Linux kernel, the following vulnerability has been resolved: arm64/sme: Set new vector length before reallocating As part of fixing the allocation of the buffer for SVE state when changing SME vector length we introduced an immediate reallocation of the SVE state, this is also done when...

CVE-2023-53184
The CVE-2023-53184 entry concerns a Linux kernel vulnerability in arm64 SME (SVE state handling). The root cause is that the vector length is updated after allocating the SVE state, causing allocation with the old length and potential memory corruption from an undersized buffer. The fix moves the...

DEBIAN-CVE-2025-38170
In the Linux kernel, the following vulnerability has been resolved: arm64/fpsimd: Discard stale CPU state when handling SME traps The logic for handling SME traps manipulates saved FPSIMD/SVE/SME state incorrectly, and a race with preemption can result in a task having TIFSME set and...

kernel: KVM: arm64: Unconditionally save+flush host FPSIMD/SVE/SME state
A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem on ARM64 architectures. The hypervisor improperly manages host floating-point and vector register states when switching context to a virtual machine. A local user with privileges to run virtual machines can exploit...
