公告ID: KYLIN-2019-14284
安全等级: 中等
产品: Kylin V3
发布日期: 2019年7月26日
CVE: CVE-2019-14284
CVSS3评分: 5.0
概述:
None 描述:
In the Linux kernel before 5.2.3, drivers/block/floppy.c allows a denial of service by setup_format_params division-by-zero. Two consecutive ioctls can trigger the bug: the first one should set the drive geometry with .sect and .rate values that make F_SECT_PER_TRACK be zero. Next, the floppy format operation should be called. It can be triggered by an unprivileged local user even when a floppy disk has not been inserted. NOTE: QEMU creates the floppy device by default. 系统版本:
