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.

Functions i2ulaw_array() in ulaw.c and i2alaw_array() in alaw.c use an attacker-controlled value to index a global array, however when the value is negative they get the opposite, which is undefined behaviour in case the original value is INT_MIN. Thus those functions could access some element
