  "description": "The Linux Kernel, the operating system core itself.\r\n\r\nSecurity Fix(es):\r\n\r\nAn array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system.(CVE-2023-42753)",
