How to Fix CVE-2026-74651

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-2026-74651, 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: staging: rtl8723bs: fix OOB read in rtw_get_wpa_ie() rtw_get_wpa_ie() reads bytes at fixed offsets into a vendor-specific information element without checking that the element is long enough, causing an out-of-bounds read for a short trailing IE. The function locates a vendor-specific IE (EID 221) with rtw_get_ie() and then compares a 4-byte OUI+type at pbuf + 2 and reads a 2-byte version word at pbuf + 6. Those accesses require the IE body to be at least 6 bytes, but rtw_get_ie() only guarantees that the element fits within the buffer; it does not enforce a minimum body length. A vendor-specific IE whose length byte is 0 to 5, placed at the end of the buffer, therefore makes these reads run past the end of the IE and past the end of the buffer itself. The buffer holds information elements taken from received management frames and from the IE blob passed to rtw_cfg80211_set_wpa_ie(), which is kmemdup'd to its exact length, so the read can run off the end of the allocation. The sibling helpers rtw_get_sec_ie(), rtw_get_wapi_ie() and rtw_get_wps_ie() in this file already reject too-short vendor-specific IEs before their OUI memcmp(); rtw_get_wpa_ie() was never brought in line with them, and needs a minimum of 6 rather than 4 bytes because of the version word. Add the missing length check.
