CVE-2025-48041 Erlang vulnerabilities
Title: Erlang vulnerabilities
Summary: Several security issues were fixed in Erlang.
It was discovered that Erlang incorrectly handled resource allocation and
consumption in the SFTP SSH module. An attacker could possibly use this
issue cause Erlang to consume excessive resources, leading to a denial of
service.
Instructions: After a standard system update you need to reboot your computer to make all
the necessary changes.

erlang: Erlang Exhaustion of File Handles
Allocation of Resources Without Limits or Throttling vulnerability in Erlang OTP ssh (ssh_sftp modules) allows Excessive Allocation, Flooding. This vulnerability is associated with program files lib/ssh/src/ssh_sftpd.erl.
This issue affects OTP form OTP 17.0 until OTP 28.0.3, OTP 27.3.4.3 and 26.2.5.15 corresponding to ssh from 3.0.1 until 5.3.3, 5.2.11.3 and 5.1.4.12.
A file handle exhaustion flaw has been discovered in the Erlang OTP. Code handling SSH_FXP_OPENDIR operation does not allocate OS level file handles, but does create a file handle in the Erlang VM.
Since the OS file handle is not created, OS level limitations will not be applied. As a result the list of file handles might grow until resource consumption of Erlang VM affects the sys

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.
