linuxptp: denial of service via a crafted Pdelay_Req message to the time synchronization function
An issue in IEEE 802.1AS linuxptp v.4.2 and before allowing a remote attacker to cause a denial of service via a crafted Pdelay_Req message to the time synchronization function
A flaw was found in Linux PTP. This flaw allows an attacker to possibly trigger a denial of service via a specially crafted Pdelay_Req message to the time synchronization function.
Statement: This vulnerability is categorized as a Moderate severity rather than Important because it specifically targets the time synchronization function on a single port rather than causing broader system or network compromise. The attack requires the attacker to be on the same Ethernet network, limiting its scope and accessibility. Add

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.
