CVE-2026-23356: Software Security Vulnerability Vulnerability
MODERATECVE-2026-23356 is a MODERATE (CVSS 5.5) security vulnerability vulnerability (CWE-617: Reachable Assertion) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary.. Remediation is available in the latest vendor maintenance releases.
CVE-2026-23356 at a Glance
Security Impact
CVSS: 5.5
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:N/I:N/A:H).
How to Fix CVE-2026-23356
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-2026-23356, 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.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-617: Reachable Assertion, where the product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary. In Software, software state validation or input boundaries are circumvented during processing.

"details" : "In the Linux kernel, the following vulnerability has been resolved:\n\ndrbd: fix \"LOGIC BUG\" in drbd_al_begin_io_nonblock()\n\nEven though we check that we \"should\" be able to do lc_get_cumulative()\nwhile holding the device->al_lock spinlock, it may still fail,\nif some other code path decided to do lc_try_lock() with bad timing.\n\nIf that happened, we logged \"LOGIC BUG for enr=...\",\nbut still did not return an error.\n\nThe rest of the code now assumed that this request has references\nfor the relevant activity log extents.\n\nThe implcations are that during an active resync, mutual exclusivity of\nresync versus application IO is not guaranteed. And a potential crash\nat this point may not realizs that these extents could have been target\nof in-flight IO and would need to be resynced just in case.\n\nAlso, once the request completes, it will give up activity log references it\ndoes not even hold, which will trigger a BUG_ON(refcnt == 0) in lc_put().\n\nFix:\n\nDo not crash the kernel for a condition that is harmless during normal\noperation: also catch \"e->refcnt == 0\", not only \"e == NULL\"\nwhen being noisy about \"al_complete_io() called on inactive extent %u\\n\".\n\nAnd do not try to be smart and \"guess\" whether something will work, then\nbe surprised when it does not.\nDeal with the fact that it may or may not work. If it does not, remember a\npossible \"partially in activity log\" state (only possible for requests that\ncross extent boundaries), and return an error code from\ndrbd_al_begin_io_nonblock().\n\nA latter call for the same request will then resume from where we left off.",
