A local attacker could use this to\ncause a denial of service or possibly execute arbitrary code.\n(CVE-2020-25669)\n\nIt was discovered that the jfs file system implementation in the Linux\nkernel contained an out-of-bounds read vulnerability. A local attacker\ncould use this to possibly cause a denial of service (system crash).\n(CVE-2020-27815)\n\nShisong Qin and Bodong Zhao discovered that Speakup screen reader driver in\nthe Linux kernel did not correctly handle setting line discipline in some\nsituations. A local attacker could use this to cause a denial of service\n(system crash). (CVE-2020-27830, CVE-2020-28941)\n\nIt was discovered that an information leak existed in the syscall\nimplementation in the Linux kernel on 32 bit systems.
