CVE-2026-2664: CWE-125 Out-of-bounds Read in Docker Docker Desktop
CVE-2026-2664 is an out-of-bounds read vulnerability in the grpcfuse kernel module within the Linux VM used by Docker Desktop on Windows, Linux, and macOS up to version 4.61.0. This vulnerability allows a local attacker with low privileges to cause an unspecified impact by writing to /proc/docker entries. The issue has been addressed and fixed in Docker Desktop version 4.62.0. The vulnerability has a CVSS 4.0 base score of 6.8, indicating a medium severity level.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-2664) involves an out-of-bounds read (CWE-125) in the grpcfuse kernel module of the Linux VM embedded in Docker Desktop for multiple platforms. The flaw permits a local attacker with low privileges to write to /proc/docker entries, potentially causing an unspecified impact. The vulnerability affects Docker Desktop versions up to 4.61.0 and was fixed in version 4.62.0. The CVSS 4.0 vector indicates local attack vector, low attack complexity, no privileges required beyond local user, no user interaction, and high impact on confidentiality.
Potential Impact
A local attacker with low privileges on the host system running Docker Desktop up to version 4.61.0 could exploit this vulnerability to perform out-of-bounds reads via the grpcfuse kernel module, leading to an unspecified impact. The exact consequences are not detailed, but the CVSS score and vector suggest potential confidentiality impact. There are no known exploits in the wild at this time.
Mitigation Recommendations
Upgrade Docker Desktop to version 4.62.0 or later, where this vulnerability has been fixed. No other mitigation or temporary workaround is indicated by the vendor advisory. Since this is not a cloud service, remediation depends on user action to update the software.
