Linux Kernel up to 7.2.5 ipvs ip_vs_ftp_get_addrport integer overflow

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Linux Kernel up to 7.2.5. It has been classified as very critical. Affected is the function ip_vs_ftp_get_addrport of the component ipvs. The manipulation with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: ipvs: fix integer overflow in ftp helper port/address parsing ip_vs_ftp_get_addrport() accumulates decimal digits into a __u16 (hport) and into unsigned char (p[]) without checking for overflow. A crafted FTP PASV/EPSV response with an over-long port or address octet wraps the value, so the helper configures the data connection with a truncated port/address. The netfilter conntrack FTP helper had the same defect, fixed in commit 2b413fc689ba ("netfilter: nf_conntrack_ftp: avoid u16 overflows"). Apply the equivalent fix here: widen the port accumulator to u32 and reject values above 65535, and reject address octets above 255.

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2026-90141 since 09/11/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $5k-$25k at the moment (estimation calculated on 09/17/2026).

Upgrading to version 5.10.270, 5.15.221, 6.1.188, 6.6.157, 6.12.110, 6.18.52, 7.2.6 or 7.3-rc1 eliminates this vulnerability. Applying the patch d02de9a7a7e2484da0cf37e50614840623b98a62/fc1493c905d7e0bc8830c1d83915cb7831daf1a1/50cb9b7263a2ed01f7d2f97818a800c2ee05f661/deaa88fa010ba0dfc554d09e006ddd1ce9945c82/00bcc6d679262ea42688fba1d7819ea6e56f12ef/4aed450adaee3a021db27be94c61fe025b0d05ff/b1908bff0faaa94d55be72da65879cad632e8236/e625a9477d12baaff4025c5f9989184a907ea8fc is able to eliminate this problem. The best possible mitigation is suggested to be upgrading to the latest version.
