Astra Linux – Vulnerability in Linux 6.1

A flaw was discovered in KVM. An improper check in svmsetx2apicmsrinterception may allow direct access to the host’s x2apic MSRs when the guest resets its APIC, potentially leading to a denial-of-service condition...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: kvm: LAPIC: The guard that prevented illegal access to the APIC register has been restored. According to SDM, “Any access that touches the bytes 4 through 15 of an APIC register may cause undefined behavior and must not be...

CVE-2026-43363

A flaw was found in the Linux kernel. When resuming from suspend to RAM s2ram, the system's firmware may incorrectly re-enable x2apic mode, even if the kernel had previously disabled it. This mismatch causes the kernel to operate with an incompatible interface, leading to system hangs and a Denia...

CVE-2026-43363

CVE-2026-43363 concerns the Linux kernel x86 APIC subsystem. If, on resume from s2ram (S2/S3 wake), firmware re-enables x2APIC mode after the kernel has booted with x2APIC disabled, the system can run with x2APIC hardware but the kernel uses the xapic interface, leading to hangs. The issue is cau...
