Summary
linux-oem-6.0 vulnerabilities
Details

It was discovered that the Traffic-Control Index (TCINDEX) implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-1281)

It was discovered that the KVM VMX implementation in the Linux kernel did not properly handle indirect branch prediction isolation between L1 and L2 VMs. An attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs. (CVE-2022-2196)

Thadeu Cascardo discovered that the io_uring subsystem contained a double- free vulnerability in certain memory allocation error conditions. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-1032)
