How to Fix CVE-2026-93098

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-2026-93098, 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: rpmsg: glink: fix deadlock in endpoint destroy during driver detach During driver detach, the device core holds the device mutex throughout the driver's remove callback chain. When the rpmsg endpoint is destroyed as part of that teardown, the GLINK endpoint destroy implementation attempts to unregister the underlying rpmsg device. That unregistration calls device_del(), which tries to re-acquire the same device mutex already held higher up the stack, causing rmmod to hang indefinitely. The deadlock manifests with the following call chain: [<0>] device_del+0x44/0x414  <- tries to acquire same mutex [<0>] device_unregister+0x18/0x34 [<0>] rpmsg_unregister_device+0x28/0x4c [<0>] qcom_glink_remove_rpmsg_device+0x70/0xc0 [<0>] qcom_glink_destroy_ept+0x58/0xbc [<0>] rpmsg_dev_remove+0x50/0x60 [<0>] device_remove+0x4c/0x80 [<0>] device_release_driver_internal+0x1cc/0x228 <- acquires device mutex [<0>] driver_detach+0x4c/0x98 [<0>] bus_remove_driver+0x6c/0xbc [<0>] driver_unregister+0x30/0x60 [<0>] unregister_rpmsg_driver+0x10/0x1c [<0>] fastrpc_exit+0x28/0x38 [fastrpc] [<0>] __arm64_sys_delete_module+0x1b8/0x294 [<0>] invoke_syscall+0x48/0x10c [<0>] el0_svc_common.constprop.0+0xc0/0xe0 [<0>] do_el0_svc+0x1c/0x28 [<0>] el0_svc+0x34/0x108 [<0>] el0t_64_sync_handler+0xa0/0xe4 [<0>] el0t_64_sync+0x198/0x19c The rpmsg device unregistration inside endpoint destroy is redundant. In both contexts where endpoint destruction is triggered: - Driver detach path: the driver core already tears down the rpmsg device. - Channel close path: the rpmsg device is already unregistered before endpoint destruction is reached. Remove the redundant unregistration to fix the deadlock.
