Ubuntu Security Notice 6027-1 - It was discovered that the Traffic-Control Index implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Jiasheng Jiang discovered that the HSA Linux kernel driver for AMD Radeon GPU devices did not properly validate memory allocation in certain situations, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service.

<p>In this article we will describe how Microsoft and Red Hat are collaborating in the open source community to show how Red Hat <a href="https://www.redhat.com/en/technologies/cloud-computing/openshift">OpenShift</a> can be deployed on <a href="https://aka.ms/azurecc">Azure Confidential Computing</a> for providing confidential container capabilities to its users. For this purpose, OpenShift uses the <a href="https://www.redhat.com/en/blog/learn-openshift-sandboxed-containe

Ubuntu Security Notice 6014-1 - Xuewei Feng, Chuanpu Fu, Qi Li, Kun Sun, and Ke Xu discovered that the TCP implementation in the Linux kernel did not properly handle IPID assignment. A remote attacker could use this to cause a denial of service or inject forged data. Ke Sun, Alyssa Milburn, Henrique Kawakami, Emma Benoit, Igor Chervatyuk, Lisa Aichele, and Thais Moreira Hamasaki discovered that the Spectre Variant 2 mitigations for AMD processors on Linux were insufficient in some situations. A local attacker could possibly use this to expose sensitive information.

It's the second Tuesday of the month, and Microsoft has released another set of security updates to fix a total of 97 flaws impacting its software, one of which has been actively exploited in ransomware attacks in the wild. Seven of the 97 bugs are rated Critical and 90 are rated Important in severity. Interestingly, 45 of the shortcomings are remote code execution flaws, followed by 20

Ubuntu Security Notice 6001-1 - Xuewei Feng, Chuanpu Fu, Qi Li, Kun Sun, and Ke Xu discovered that the TCP implementation in the Linux kernel did not properly handle IPID assignment.

In Docker Desktop 4.17.x the Artifactory Integration falls back to sending registry credentials over plain HTTP if the HTTPS health check has failed. A targeted network sniffing attack can lead to a disclosure of sensitive information. Only users who have Access Experimental Features enabled and have logged in to a private registry are affected.

Ubuntu Security Notice 5978-1 - It was discovered that the network queuing discipline implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. 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.
