A local attacker\ncould use this to possibly cause a denial of service (system crash).\n(CVE-2020-27815)\n\nIt was discovered that the memory management subsystem in the Linux kernel\ndid not properly handle copy-on-write operations in some situations. A\nlocal attacker could possibly use this to gain unintended write access to\nread-only memory pages. (CVE-2020-29374)\n\nMichael Kurth and Pawel Wieczorkiewicz discovered that the Xen event\nprocessing backend in the Linux kernel did not properly limit the number of\nevents queued. An attacker in a guest VM could use this to cause a denial\nof service in the host OS. (CVE-2020-29568)\n\nJann Horn discovered that the tty subsystem of the Linux kernel did not use\nconsistent locking in some situations, leading to a read-after-free\nvulnerability.
