CVE-2024-35980

The CVE-2024-35980 issue affects the Linux kernel on arm64 when KVM is involved. The root cause is a TLBI RANGE operand sorting bug: the value passed to TLBI RANGE was not correctly derived during live migration, causing incomplete TLB flushing and potential crashes on the destination VM or misse...

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, which stems from an incorrect ordering of operands passed to the TLBI RANGE instruction, which can cause the target virtual...
