A local attacker could possibly use this to gain elevated\nprivileges. Please note that with the fix for this CVE, kernel support for\nthe TCINDEX classifier has been removed. (CVE-2023-1829)\n\nLin Ma discovered a race condition in the io_uring subsystem in the Linux\nkernel, leading to a null pointer dereference vulnerability. A local\nattacker could use this to cause a denial of service (system crash).\n(CVE-2023-0468)\n\nIt was discovered that the OverlayFS implementation in the Linux kernel did\nnot properly handle copy up operation in some conditions. A local attacker\ncould possibly use this to gain elevated privileges. (CVE-2023-0386)\n\nIt was discovered that a race condition existed in the Xen transport layer\nimplementation for the 9P file system protocol in the Linux kernel, leading\nto a use-after-free vulnerability. A local attacker could use this to cause\na denial of service (guest crash) or expose sensitive information (guest\nkernel memory). (CVE-2023-1859)\n\nKyle Zeng discovered that the ATM VC queuing discipline implementation in\nthe Linux kernel contained a type confusion vulnerability in some\nsituations. An attacker could use this to cause a denial of service (system\ncrash). (CVE-2023-23455)\n\nLianhui Tang discovered that the MPLS implementation in the Linux kernel\ndid not properly handle certain sysctl allocation failure conditions,\nleading to a double-free vulnerability. An attacker could use this to cause\na denial of service or possibly execute arbitrary code.
