漏洞描述
中文描述:

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel 5.3及之前版本中的KVM虚拟机监视器的实现存在缓冲区错误漏洞。攻击者可利用该漏洞造成主机内核崩溃，导致拒绝服务或可能提升权限。

英文描述:

An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system.
