Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a failure to set a new vector length before reallocating the SVE status buffer, which could lead to memory...

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from the AVX-512 state function not checking for NULL pointers...

DEBIAN-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...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: KVM: arm64: Unconditionally save+flush host FPSIMD/SVE/SME state There are several issues with the way the hyp code lazily saves the host’s FPSIMD/SVE state. These include: The host SVE state is unexpectedly discarded due to...

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from not properly saving host FPSIMD/SVE/SME state, which could lead to a QEMU crash or ptrace ABI change...

kernel: arm64/sve: Discard stale CPU state when handling SVE traps

In the Linux kernel, the following vulnerability has been resolved: arm64/sve: Discard stale CPU state when handling SVE traps The logic for handling SVE traps manipulates saved FPSIMD/SVE state incorrectly, and a race with preemption can result in a task having TIFSVE set and TIFFOREIGNFPSTATE...

hw: arm64/sme: Always exit sme_alloc() early with existing storage

In the Linux kernel, the following vulnerability has been resolved: arm64/sme: Always exit smealloc early with existing storage When smealloc is called with existing storage and we are not flushing we will always allocate new storage, both leaking the existing storage and corrupting the state. Fi...

GhostWrite: New T-Head CPU Bugs Expose Devices to Unrestricted Attacks

A team of researchers from the CISPA Helmholtz Center for Information Security in Germany has disclosed an architectural bug impacting Chinese chip company T-Head's XuanTie C910 and C920 RISC-V CPUs that could allow attackers to gain unrestricted access to susceptible devices. The vulnerability h...

hw: Vector Register Leakage-Active

A flaw was found in the Intel Advanced Vector Extensions AVX implementation, where a local authenticated attacker with the ability to execute AVX instructions can gather the AVX register state from previous AVX executions. This vulnerability allows information disclosure of the AVX register state...
