"summary": "linux-azure-5.15, linux-azure-fde, linux-kvm vulnerabilities",
"details": "It was discovered that the Traffic-Control Index (TCINDEX) implementation\nin the Linux kernel did not properly perform filter deactivation in some\nsituations. 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\nIt was discovered that a race condition existed in the io_uring subsystem\nin the Linux kernel, leading to a use-after-free vulnerability. A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2023-1872)\n\n",
