CVE-2026-45933

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier. The synclinkedregs function fails to preserve the register ID during bounds propagation, which can lead to incorrect register state. This issue may allow a local attacker to trigger a 'division by zero' error, resulting i...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from hypercalls disrupting the register state, potentially leading to page faults...

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-988849 advisory. In the Linux kernel, the following vulnerability has been resolved: net: hns3: fix use-after-free bug in hclgevfsendmbxmsg Currently, the hns3remove function firstly...

DEBIAN-CVE-2023-53326

In the Linux kernel, the following vulnerability has been resolved: powerpc: Don't try to copy PPR for task with NULL ptregs powerpc sets up PFKTHREAD and PFIOWORKER with a NULL ptregs, which from my arguably very short checking is not commonly done for other archs. This is fine, except when...

CVE-2023-53326

CVE-2023-53326 affects the PowerPC Linux kernel. It stems from PF_KTHREAD/PF_IO_WORKER tasks with a NULL pt_regs, causing a NULL pointer dereference during core dump (kernel crash). The fix adds pt_regs validity checks in ppc_get/ppr_set and returns -EINVAL if pt_regs are not set. Remediation is ...

Open5GS Denial of Service Vulnerability (CNVD-2025-18575)

Open5GS is Open5GS open source an open source implementation in C of 5G Core and Epc, the core network of the Lte/Nr network. Open5GS suffers from a denial of service vulnerability that can be exploited by an attacker to cause a crash caused by the AMF in commonregisterstate...

CVE-2023-22615

An issue was discovered in IhisiSmm in Insyde InsydeH2O with kernel 5.0 through 5.5. IHISI subfunction execution may corrupt SMRAM. An attacker can pass an address in the RCX save state register that overlaps SMRAM, thereby coercing an IHISI subfunction handler to overwrite private SMRAM...

CVE-2021-47226

In the Linux kernel, the following vulnerability has been resolved: x86/fpu: Invalidate FPU state after a failed XRSTOR from a user buffer Both Intel and AMD consider it to be architecturally valid for XRSTOR to fail with PF but nonetheless change the register state. The actual conditions under...

SUSE CVE-2015-8555

Xen 4.6.x, 4.5.x, 4.4.x, 4.3.x, and earlier do not initialize x86 FPU stack and XMM registers when XSAVE/XRSTOR are not used to manage guest extended register state, which allows local guest domains to obtain sensitive information from other domains via unspecified vectors...
