Summary

linux, linux-aws, linux-azure, linux-gcp, linux-hwe-5.19, linux-ibm, linux-kvm, linux-lowlatency, linux-oracle, linux-raspi vulnerabilities

Details

It was discovered that the Traffic-Control Index (TCINDEX) implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier has been removed. (CVE-2023-1829)

It was discovered that the OverlayFS implementation in the Linux kernel did not properly handle copy up operation in some conditions. A local attacker could possibly use this to gain elevated privileges. (CVE-2023-0386)
