CVE-2017-14051

Published: 31 August 2017

An integer overflow in the qla2x00_sysfs_write_optrom_ctl function in drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel through 4.12.10 allows local users to cause a denial of service (memory corruption and system crash) by leveraging root access.

From the Ubuntu Security Team

It was discovered that an integer overflow existed in the sysfs interface for the QLogic 24xx+ series SCSI driver in the Linux kernel. A local privileged attacker could use this to cause a denial of service (system crash).
