How to Fix CVE-2026-93190

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-2026-93190, 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: platform/chrome: cros_ec_typec: Reject out-of-bounds PD cap count cros_typec_register_partner_pdos() copies the partner PDOs from the EC TYPEC_STATUS response into the fixed caps_desc.pdo[PDO_MAX_OBJECTS] array. memcpy(caps_desc.pdo, resp->source_cap_pdos, sizeof(u32) * resp->source_cap_count); ... memcpy(caps_desc.pdo, resp->sink_cap_pdos, sizeof(u32) * resp->sink_cap_count); PDO_MAX_OBJECTS is 7. source_cap_count and sink_cap_count are u8 fields from the EC. The only check is that they are not both zero. If either is larger than 7, the memcpy writes past the end of the array on the stack. A count of 255 overflows it by about 1 KB. The EC source arrays are only seven entries wide. A larger count reads past them too. The ChromeOS EC firmware caps these counts today, so a compliant setup does not hit this. The kernel should still validate these values rather than trust them. Validate the counts in cros_typec_register_partner_pdos() next to the memcpy. Skip the PDO registration if either count is above PDO_MAX_OBJECTS. The rest of cros_typec_handle_status() still runs so events are handled and cleared.
