How to Fix CVE-2026-93263

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-2026-93263, 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: clk: eswin: Zero-initialize stack-allocated clk_init_data eswin_clk_register_pll() and eswin_register_clkdiv() declare a struct clk_init_data on the stack and only initialize some of its fields (parent_data respectively parent_hws). clk_core_populate_parent_map() checks parent_names first and parent_data second before falling back to parent_hws, so leftover stack garbage in the uninitialized fields hijacks parent resolution and the clk core dereferences a bogus pointer: Unable to handle kernel NULL pointer dereference at virtual address 000000000000000c Oops [#1] epc : __clk_register+0x31a/0x7f0 [<ffffffff805dc774>] __clk_register+0x31a/0x7f0 [<ffffffff805dcd76>] devm_clk_hw_register+0x2a/0x94 [<ffffffff805e319a>] eswin_register_clkdiv+0x80/0xd0 [<ffffffff805e34a0>] eswin_clk_register_clks+0x162/0x1a0 [<ffffffff805e3736>] eic7700_clk_probe+0x146/0x180 [<ffffffff8065d23c>] platform_probe+0x3c/0x7a Observed on EIC7700 hardware (with the driver backported to a 6.17 tree); whether the bug triggers depends entirely on what the stack happens to contain when the registration helpers run. Zero-initialize both structures.
