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 not properly loading the TSC multiplier for L1, which could lead to an error in the calculation of the...
Citrix XenServer Multiple Vulnerabilities (XSA-472)
According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by multiple vulnerabilities: - A NULL pointer dereference in the updating of the reference TSC area. CVE-2025-27466 - A NULL pointer dereference by assuming the SIM page is mapped when a...
Linux Distros Unpatched Vulnerability : CVE-2023-31347
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Due to a code bug in SecureTSC, SEV firmware may allow an attacker with high privileges to cause a guest to observe an incorrect TSC when Secure TSC is enabled...
CVE-2025-38508
In the Linux kernel, the following vulnerability has been resolved: x86/sev: Use TSCFACTOR for Secure TSC frequency calculation When using Secure TSC, the GUESTTSCFREQ MSR reports a frequency based on the nominal P0 frequency, which deviates slightly typically 0.2% from the actual mean TSC...

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 Secure TSC frequency calculations not using TSCFACTOR, which could result in inaccurate timing...
DEBIAN-CVE-2024-36349
A transient execution vulnerability in some AMD processors may allow a user process to infer TSCAUX even when such a read is disabled, potentially resulting in information leakage...
PT-2025-33551
Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The Linux kernel contains a flaw related to Secure TSC frequency calculation in SEV-SNP VMs. The GUEST TSC FREQ MSR reports a frequency based on the nominal P0 frequency, which deviate...
kernel: KVM: nSVM: Check instead of asserting on nested TSC scaling support
In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Check instead of asserting on nested TSC scaling support Check for nested TSC scaling support on nested SVM VMRUN instead of asserting that TSC scaling is exposed to L1 if L1's MSRAMD64TSCRATIO has diverged from KVM's...
PT-2024-12276
Name of the Vulnerable Software and Affected Versions SEV firmware affected versions not specified Description A code bug in Secure TSC may allow an attacker with high privileges to cause a guest to observe an incorrect TSC when Secure TSC is enabled, potentially resulting in a loss of guest...
kernel: KVM: LAPIC: Also cancel preemption timer during SET_LAPIC
A vulnerability was found in the Linux kernel's KVM component related to the LAPIC during the guest reboot process. This issue arises when the SETLAPIC command is issued without exposing the tsc-deadline mode, leading to warnings and potential inconsistencies due to an unhandled preemption timer...
