CVE-2016-4998

HIGH7.1

The IPT_SO_SET_REPLACE setsockopt implementation in the netfilter subsystem in the Linux kernel before 4.6 allows local users to cause a denial of service (out-of-bounds read) or possibly obtain sensitive information from kernel heap memory by leveraging in-container root access to provide a crafted offset value that leads to crossing a ruleset blob boundary.

CVE-2016-6130

MEDIUM4.7

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.

CVE-2016-9754

HIGH7.8

The ring_buffer_resize function in kernel/trace/ring_buffer.c in the profiling subsystem in the Linux kernel before 4.6.1 mishandles certain integer calculations, which allows local users to gain privileges by writing to the /sys/kernel/debug/tracing/buffer_size_kb file.

CVE-2017-7273

MEDIUM6.6

The cp_report_fixup function in drivers/hid/hid-cypress.c in the Linux kernel 3.2 and 4.x before 4.9.4 allows physically proximate attackers to cause a denial of service (integer underflow) or possibly have unspecified other impact via a crafted HID report.
