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 informatio

CVE-2023-41910 [CRITICAL] CWE-125 lldpd: CDP PDU Packet cdp.c out-of-bounds read
lldpd: CDP PDU Packet cdp.c out-of-bounds read
An issue was discovered in lldpd before 1.0.17. By crafting a CDP PDU packet with specific CDP_TLV_ADDRESSES TLVs, a malicious actor can remotely force the lldpd daemon to perform an out-of-bounds read on heap memory. This occurs in cdp_decode in daemon/protocols/cdp.c.
A flaw was found in lldpd due to an out-of-bounds read in cdp_decode at daemon/protocols/cdp.c. By sending a specially crafted CDP PDU packet with specific CDP_TLV_ADDRESSES TLVs, a remote attacker could cause a denial of service.
Statement: The highest threat from this vulnerability is system availability.
