  "description": "The Linux Kernel, the operating system core itself.\n\nSecurity Fix(es):\n\nAn issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvb_net.c has a .disconnect versus dvb_device_open race condition that leads to a use-after-free.(CVE-2022-45886)\n\nA use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c.\n\nMishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue.\n\nWe recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97.(CVE-2023-3390)\n\nLinux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace(CVE-2023-35001)",
