{"id":"USN-5977-1","summary":"linux-oem-6.0 vulnerabilities","details":"It was discovered that the Traffic-Control Index (TCINDEX) implementation\nin the Linux kernel contained 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-2023-1281)\n\nIt was discovered that the KVM VMX implementation in the Linux kernel did\nnot properly handle indirect branch prediction isolation between L1 and L2\nVMs. An attacker in a guest VM could use this to expose sensitive\ninformation from the host OS or other guest VMs. (CVE-2022-2196)\n\nThadeu Cascardo discovered that the io_uring subsystem contained a double-\nfree vulnerability in certain memory allocation error conditions. A local\nattacker could possibly use this to cause a denial of service (system\ncrash).
