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.

address_space_map in exec.c in QEMU 4.2.0 can trigger a NULL pointer dereference related to BounceBuffer.
A NULL pointer dereference flaw was found in the MegaRAID SAS 8708EM2 emulator of the QEMU. This issue occurs because the address_space_map() API while mapping physical memory into the host's virtual address space, may return NULL without setting the length parameter to zero (0). This flaw allows a guest user or process to crash the QEMU process on the host resulting in a denial of service.
Statement: In Red Hat OpenStack Platform, because the flaw has a lower impact and the fix would require a substantial amount of development, no update will be provided at this time for the RHOSP qemu-kvm-rhe
