CVE-2026-31445: Software Security Vulnerability Vulnerability
MODERATECVE-2026-31445 is a MODERATE (CVSS 5.5) security vulnerability vulnerability (CWE-476: NULL Pointer Dereference) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product dereferences a pointer that it expects to be valid but is null.. Remediation is available in the latest vendor maintenance releases.
CVE-2026-31445 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-2026-31445
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:tree
How to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-31445, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree
Analyze 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\nmm/damon/core: avoid use of half-online-committed context\n\nOne major usage of damon_call() is online DAMON parameters update. It is\ndone by calling damon_commit_ctx() inside the damon_call() callback\nfunction. damon_commit_ctx() can fail for two reasons: 1) invalid\nparameters and 2) internal memory allocation failures. In case of\nfailures, the damon_ctx that attempted to be updated (commit destination)\ncan be partially updated (or, corrupted from a perspective), and therefore\nshouldn't be used anymore. The function only ensures the damon_ctx object\ncan safely deallocated using damon_destroy_ctx().\n\nThe API callers are, however, calling damon_commit_ctx() only after\nasserting the parameters are valid, to avoid damon_commit_ctx() fails due\nto invalid input parameters. But it can still theoretically fail if the\ninternal memory allocation fails. In the case, DAMON may run with the\npartially updated damon_ctx. This can result in unexpected behaviors\nincluding even NULL pointer dereference in case of damos_commit_dests()\nfailure [1]. Such allocation failure is arguably too small to fail, so\nthe real world impact would be rare. But, given the bad consequence, this\nneeds to be fixed.\n\nAvoid such partially-committed (maybe-corrupted) damon_ctx use by saving\nthe damon_commit_ctx() failure on the damon_ctx object. For this,\nintroduce damon_ctx->maybe_corrupted field. damon_commit_ctx() sets it\nwhen it is failed. kdamond_call() checks if the field is set after each\ndamon_call_control->fn() is executed. If it is set, ignore remaining\ncallback requests and return. All kdamond_call() callers including\nkdamond_fn() also check the maybe_corrupted field right after\nkdamond_call() invocations. If the field is set, break the kdamond_fn()\nmain loop so that DAMON sill doesn't use the context that might be\ncorrupted.\n\n[sj@kernel.org: let kdamond_call() with cancel regardless of maybe_corrupted]",
