How to Fix CVE-2026-93039

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.

Verify Direct and Transitive Dependencies

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-2026-93039, 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.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In the Linux kernel, the following vulnerability has been resolved: ASoC: meson: Keep link pointers valid on realloc failure meson_card_reallocate_links() grows the DAI link and private data arrays with two consecutive krealloc() calls and updates the owner pointers only after both calls have succeeded. A successful krealloc() may move the data: it frees the old block and returns a new one. When that happens for the link array and the second krealloc() then fails, card->dai_link still points to the block that krealloc() already freed, and the error path frees the new block too. The probe error path then calls meson_card_clean_references(), which dereferences card->dai_link and kfree()s it again, resulting in a use-after-free and a double free. Commit card->dai_link and card->num_links right after the first krealloc() succeeds, so the pointer always refers to a valid allocation that meson_card_clean_references() can walk and free. krealloc() with __GFP_ZERO zero-initializes the added entries, so walking them on the error path is safe. With both failure paths reduced to a plain return, drop the goto labels and the error message.
