CVE-2016-6130
Published: 3 July 2016
Race condition in the sclp_ctl_ioctl_sccb function in drivers/s390/char/sclp_ctl.c in the Linux kernel before 4.6 allows local users to obtain sensitive information from kernel memory by changing a certain length value, aka a "double fetch" vulnerability.
From the Ubuntu Security Team
Pengfei Wang discovered a race condition in the s390 SCLP console driver for the Linux kernel when handling ioctl()s. A local attacker could use this to obtain sensitive information from kernel memory.
