kernel: Linux kernel KVM: Denial of Service in nested SVM due to TSC multiplier manipulation

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM nested SVM nSVM module. A local attacker with low privileges in a nested virtual machine can manipulate the Timestamp Counter TSC multiplier and CPUID features. This manipulation can trigger a kernel warning, leading to a...

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...

kernel: Linux kernel igb driver: Denial of Service due to improper SR-IOV cleanup

A flaw was found in the Linux kernel's igb driver. When the igb module is loaded with Single Root I/O Virtualization SR-IOV enabled on certain network adapters, and the SR-IOV initialization subsequently fails, the driver does not properly clean up allocated resources. A local user can exploit th...
