FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

redis: Redis Unauthenticated Denial of Service
Redis is an open source, in-memory database that persists on disk. An unauthenticated connection can cause repeated IP protocol errors, leading to client starvation and, ultimately, a denial of service. This vulnerability is fixed in 8.0.3, 7.4.5, 7.2.10, and 6.2.19.
A flaw was found in Redis. Unauthenticated connections can trigger repeated IP protocol errors, leading to client starvation and an application-level denial of service. This flaw allows an attacker to induce this condition without authentication. This issue results in a denial of service condition for connected clients. The root cause is related to the improper handling of network traffic.
Statement: The severity of this vulnerability is rated Moderate as it does not impact sys
