Security Impact
CVSS: 7.1
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N).
How to Fix CVE-2026-46054
To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:treeHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-46054, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:treeAnalyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

"details" : "In the Linux kernel, the following vulnerability has been resolved:\n\nselinux: fix overlayfs mmap() and mprotect() access checks\n\nThe existing SELinux security model for overlayfs is to allow access if\nthe current task is able to access the top level file (the \"user\" file)\nand the mounter's credentials are sufficient to access the lower\nlevel file (the \"backing\" file). Unfortunately, the current code does\nnot properly enforce these access controls for both mmap() and mprotect()\noperations on overlayfs filesystems.\n\nThis patch makes use of the newly created security_mmap_backing_file()\nLSM hook to provide the missing backing file enforcement for mmap()\noperations, and leverages the backing file API and new LSM blob to\nprovide the necessary information to properly enforce the mprotect()\naccess controls.",
