CVE-2026-64513
A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for x86 architectures. When the apicupdateppr function does not find a deliverable interrupt, it fails to recompute the CR8 intercept, leading to a stale Task Priority Register Threshold TPRTHRESHOLD. This issue can cause a...

CVE-2026-43483
CVE-2026-43483 (Linux kernel, KVM/VMX-SVM) fixes a flaw in SVM AVIC handling where CR8 write interception could remain enabled after AVIC activation. The patch explicitly sets/clears CR8 interception when AVIC is (de)activated to prevent the dangling intercept, which could cause TPR desynchroniza...

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel-rt packages installed that are affected by multiple vulnerabilities: - Integer overflow in the aiosetupsinglevector function in fs/aio.c in the Linux kernel 4.0 allows local users to cause a denial of service or...
USN-3698-1 linux vulnerabilities
It was discovered that the nested KVM implementation in the Linux kernel in some situations did not properly prevent second level guests from reading and writing the hardware CR8 register. A local attacker in a guest could use this to cause a denial of service system crash. CVE-2017-12154 Fan Wu,...
Kernel: kvm: nVMX: L2 guest could access hardware(L0) CR8 register
Linux kernel built with the KVM visualization support CONFIGKVM, with nested visualization nVMX feature enabled nested=1, is vulnerable to a crash due to disabled external interrupts. As L2 guest could access r/w hardware CR8 register of the hostL0. In a nested visualization setup, L2 guest user...
