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.

hunspell: out-of-bounds read in SuggestMgr::leftcommonsubstring in suggestmgr.cxx
Hunspell 1.7.0 has an invalid read operation in SuggestMgr::leftcommonsubstring in suggestmgr.cxx.
Statement: This is unlikely to be an issue in a real world scenario, as it requires specially crafted Hunspell dictionaries, which are not shipped with Red Hat Enterprise Linux. Additionally, applications using Hunspell will likely filter out invalid input before passing it on, which further limits the impact.
