**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
A vulnerability has been resolved in the Linux kernel related to the arm64: tlb: Fix TLBI RANGE operand. The issue arises when the KVM/arm64 relies on the TLBI RANGE feature to flush TLBs during live migration, but the operand passed to the TLBI RANGE instruction is not correctly sorted out. This leads to a crash on the destination VM after live migration because TLBs are not flushed completely, and some dirty pages are missed. The problem is caused by the commit 117940aa6e5f, which defined `kvm tlb flush vmid range()`. The fix involves extending ` TLBI RANGE NUM()` to support the combination of SCALE#3 and NUM#31.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
