How to Fix CVE-2026-98824

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-2026-98824, 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: wifi: mac80211: validate TX status rate metadata minstrel_ht_tx_status() converts the HT/VHT rate reported in a TX status into a group and rate index and uses those to index the minstrel_ht rate tables. The existing validation only checked that an entry was present and had tries recorded; it did not check that the reported MCS, spatial stream count and bandwidth are representable by the tables, so malformed metadata passed to minstrel_ht_get_stats() or minstrel_ht_ri_get_stats() could be used as an out-of-bounds index. Validate the rate metadata in the common TX status path instead of only in minstrel_ht, since the values are used by more than rate control. The legacy ieee80211_tx_rate array and the rate_info based entries are sanitized in ieee80211_tx_status_ext() and ieee80211_tx_rate_update() before any consumer runs: an entry that does not describe a valid rate for its encoding is dropped. minstrel_ht keeps the checks that depend on its own tables, i.e. the supported number of spatial streams, the MCS group size and the supported bandwidths. This does not take away the driver's responsibility to report sane values, it only prevents a single bad report from corrupting mac80211 state. No WARN_ON() is added: with panic_on_warn a driver bug would otherwise turn into a denial of service.
