CVE-2018-20669 [HIGH] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Timothy Michaud discovered that the i915 graphics driver in the Linux
kernel did not properly validate user memory locations for the
i915_gem_execbuffer2_ioctl. A local attacker could possibly use this to
cause a denial of service or execute arbitrary code. (CVE-2018-20669)
It was discovered that the Kvaser CAN/USB driver in the Linux kernel did
not properly initialize memory in certain situations. A local attacker
could possibly use this to expose sensitive information (kernel memory).

In the Linux kernel through 5.4.6, there are information leaks of uninitialized memory to a USB device in the drivers/net/can/usb/kvaser_usb/kvaser_usb_leaf.c driver, aka CID-da2311a6385c.
A flaw was found in the Linux kernel in versions through 5.4.6, containing information leaks of uninitialized memory to a USB device. The latest findings show that the uninitialized memory allocation was not leading to an information leak, but was allocating the memory assigned with data on the next line and hence causing no violation.
Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comp
