This Week in Spring - June 6th, 2023

Hi, Spring fans! Welcome to another installment of This Week in Spring! And what an insane week it's been! Long story short, I've spent 10-12 hours a day over the last five days migrating a dozen differnet applications and services from one GKE cluster to another, taking the time to update things...

Use Of Uninitialized Variable

linux-gke is vulnerable to Use of Uninitialized Variable. The vulnerability allows users with the ability to execute high-privileged code to exploit the flaws within 'nftosfeval function' causing a lack of proper initialization of memory prior to accessing it resulting in the attacker gaining...

USN-6027-1: Linux kernel vulnerabilities

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 Jiasheng Jiang discovered that the HSA...

USN-6025-1: Linux kernel vulnerabilities

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 OverlayFS...

USN-5987-1: Linux kernel vulnerabilities

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 It was discovered...
