Ubuntu Security Notice 4485-1 - 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. 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. Various other issues were also addressed.
3eab8c5a9aa035dc793457aedf9c3e72Ubuntu Security Notice 4483-1 - Chuhong Yuan discovered that go7007 USB audio device driver in the Linux kernel did not properly deallocate memory in some failure conditions. A physically proximate attacker could use this to cause a denial of service. Fan Yang discovered that the mremap implementation in the Linux kernel did not properly handle DAX Huge Pages. A local attacker with access to DAX storage could use this to gain administrative privileges. Various other issues were also addressed.
956d025e726890073a04c74a86361f70Red Hat Security Advisory 2020-3297-01 - This is a kernel live patch module which is automatically loaded by the RPM post-install script to modify the code of a running kernel.
dea081405f874171c184d5a14d17c67aRed Hat Security Advisory 2020-3222-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Issues addressed include buffer overflow, bypass, denial of service, and use-after-free vulnerabilities.
c02ad005e8a5b5594ac671c959f4f4b3Ubuntu Security Notice 4440-1 - It was discovered that the network block device implementation in the Linux kernel did not properly check for error conditions in some situations. An attacker could possibly use this to cause a denial of service. It was discovered that the kernel->user space relay implementation in the Linux kernel did not properly check return values in some situations. A local attacker could possibly use this to cause a denial of service. Various other issues were also addressed.
84023413bcd0b80225be255d04f167ccUbuntu Security Notice 4439-1 - It was discovered that the network block device implementation in the Linux kernel did not properly check for error conditions in some situations. An attacker could possibly use this to cause a denial of service. It was discovered that the btrfs file system implementation in the Linux kernel did not properly validate file system metadata in some situations. An attacker could use this to construct a malicious btrfs image that, when mounted, could cause a denial of service. Various other issues were also addressed.
