The vulnerability of the vgicitsrestoredte function in the arch/arm64/kvm/vgic/vgic-its.c module of the ARM 64-bit kernel-based Linux operating system involves the execution of operations outside the buffer boundaries in memory. Exploiting this vulnerability could allow an attacker to access...

Linux ARM64 KVM DoS

The vulnerability in the kvmarchvcpucreate function within the arch/arm64/kvm/arm.c file of the ARM virtualization subsystem on Linux 64-bit operating systems is related to a resource leak that occurs after the expiration of its valid usage period. Exploitation of this vulnerability may allow an...

ARM 64-bit kernel Heap Buffer Overflow DoS

The vulnerability of the freehotplugpagerange function in the arch/arm64/mm/mmu.c module of the ARM 64-bit kernel support for the Linux operating system is related to improper resource release. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2026-50185 RustCrypto Cmov/CmovEq on aarch64 can produce wrong results if high-bits of registers are set

RustCrypto CMOV provides conditional move CPU intrinsics which are guaranteed on major platforms to execute in constant-time and not be rewritten as branches by the compiler. From 0.1.1 until 0.5.4, the aarch64 implementations of Cmov and CmovEq in cmov/src/backends/aarch64.rs assume high bits ar...

USN-8492-4: Linux kernel (Raspberry Pi) vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - MIPS architecture; - PowerPC architecture; - x86 architecture; - Block layer subsystem; -...

DEBIAN-CVE-2026-6330

The ML-KEM ARM64 NEON ciphertext comparison only compares half of the input, breaking the Fujisaki-Okamoto transform's implicit rejection and weakening IND-CCA2 security on that code path. The constant-time comparison effectively ignored part of the re-encrypted ciphertext, so a decapsulating par...

CVE-2026-46147 KVM: arm64: Fix pin leak and publication ordering in __pkvm_init_vcpu()

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Fix pin leak and publication ordering in pkvminitvcpu Two bugs exist in the vCPU initialisation path: 1. If a check fails after hyppinsharedmem succeeds, the cleanup path jumps to 'unlock' without calling unpinhostvcp...

CVE-2026-45876

In the Linux kernel, the following vulnerability has been resolved: arm64/gcs: Fix error handling in archsetshadowstackstatus allocgcs returns an error-encoded pointer on failure, which comes from dommap, not NULL. The current NULL check fails to detect errors, which could lead to using an invali...

RUSTSEC-2026-0212 Potentially Incorrect Output of Constant-Time Swap/Select on Aarch64

The implementation of constant-time swap and select on aarch64 platforms used a cmp instruction in inline assembly to check whether an 8-bit wide selector was 0. The cmp instruction works on 32-bit registers, which included the unspecified high 24 bits of the cmp operand. Depending on the executi...
