"details": "Zheng Zhang discovered that the device-mapper implementation in the Linux\nkernel did not properly handle locking during table_clear() operations. A\nlocal attacker could use this to cause a denial of service (kernel\ndeadlock). (CVE-2023-2269)\n\nIt was discovered that a use-after-free vulnerability existed in the HFS+\nfile system implementation in the Linux kernel. A local attacker could\npossibly use this to cause a denial of service (system crash).\n(CVE-2023-2985)\n\nIt was discovered that the DVB Core driver in the Linux kernel did not\nproperly handle locking events in certain situations. A local attacker\ncould use this to cause a denial of service (kernel deadlock).\n(CVE-2023-31084)\n\nIt was discovered that the virtual terminal driver in the Linux kernel\ncontained a use-after-free vulnerability. A local attacker could use this\nto cause a denial of service (system crash) or possibly expose sensitive\ninformation (kernel memory). (CVE-2023-3567)\n\nIt was discovered that the Quick Fair Queueing network scheduler\nimplementation in the Linux kernel contained an out-of-bounds write\nvulnerability. A local attacker could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2023-3611)\n\nIt was discovered that the network packet classifier with\nnetfilter/firewall marks implementation in the Linux kernel did not\nproperly handle reference counting, 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-2023-3776)\n\n",
