  "details": "It was discovered that the Linux kernel did not properly restrict access to\nthe kernel debugger when booted in secure boot environments. A privileged\nattacker could use this to bypass UEFI Secure Boot restrictions.\n(CVE-2022-21499)\n\nAaron Adams discovered that the netfilter subsystem in the Linux kernel did\nnot properly handle the removal of stateful expressions in some situations,\nleading to a use-after-free vulnerability. A local attacker could use this\nto cause a denial of service (system crash) or execute arbitrary code.\n(CVE-2022-1966)\n\nMinh Yuan discovered that the floppy driver in the Linux kernel contained a\nrace condition in some situations, leading to a use-after-free\nvulnerability. A local attacker could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2022-1836)\n\nZiming Zhang discovered that the netfilter subsystem in the Linux kernel\ndid not properly validate sets with multiple ranged fields. A local\nattacker could use this to cause a denial of service or execute arbitrary\ncode. (CVE-2022-1972)\n",
