"details": "Marek Marczykowski-G\u00f3recki discovered that the Xen event channel\ninfrastructure implementation in the Linux kernel contained a race\ncondition. An attacker in a guest VM could possibly use this to cause a\ndenial of service (paravirtualized device unavailability). (CVE-2023-34324)\n\nZheng Wang discovered a use-after-free in the Renesas Ethernet AVB driver\nin the Linux kernel during device removal. A privileged attacker could use\nthis to cause a denial of service (system crash). (CVE-2023-35827)\n\nIt was discovered that a race condition existed in the Linux kernel when\nperforming operations with kernel objects, leading to an out-of-bounds\nwrite. A local attacker could use this to cause a denial of service (system\ncrash) or execute arbitrary code. (CVE-2023-45863)\n\n\u9ec4\u601d\u806a discovered that the NFC Controller Interface (NCI) implementation in\nthe Linux kernel did not properly handle certain memory allocation failure\nconditions, leading to a null pointer dereference vulnerability. A local\nattacker could use this to cause a denial of service (system crash).\n(CVE-2023-46343)\n",
