CVE-2016-6130: 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…
Noroxi assessment
Priority: Monitor (action score 18/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.27% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
- Fixed version: linux (Debian:12) 4.6.1-1; linux (Debian:8) 3.16.7-ckt25-2+deb8u3; kernel-default (SUSE:Linux Enterprise Desktop 12 SP1) 3.12.67-60.64.18.1.
Low priority for now. Upgrade to linux (Debian:12) 4.6.1-1; linux (Debian:8) 3.16.7-ckt25-2+deb8u3; kernel-default (SUSE:Linux Enterprise Desktop 12 SP1) 3.12.67-60.64.18.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
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.
