How to Fix CVE-2026-80762

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-2026-80762, 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: Bluetooth: hci_sync: Fix accept list UAF during suspend hci_update_event_filter_sync() walks hdev->accept_list while sending a synchronous HCI command for each remote-wakeup device. The suspend path holds hdev->req_lock, but accept-list updates are serialized by hdev->lock. Consequently, remove_device() can free the current list entry during the controller wait. The following interleaving causes the use-after-free: hci_update_event_filter_sync() remove_device() fetch accept-list entry hci_set_event_filter_sync() wait for controller response hci_dev_lock() list_del() kfree() hci_dev_unlock() read the freed list.next KASAN reported: BUG: KASAN: slab-use-after-free in hci_suspend_sync+0x835/0x910 Read of size 8 at addr ffff88810bec8440 by task kworker/0:1/10 Workqueue: events vhci_suspend_work Call Trace: hci_suspend_sync+0x835/0x910 hci_suspend_dev+0x182/0x450 process_one_work+0x661/0x1090 worker_thread+0x45b/0xd10 Allocated by task 86: hci_bdaddr_list_add_with_flags+0x1a8/0x400 add_device+0x381/0x820 hci_sock_sendmsg+0x1033/0x1ea0 Freed by task 91: kfree+0x131/0x3c0 remove_device+0x429/0xb70 hci_sock_sendmsg+0x1033/0x1ea0 Snapshot the remote-wakeup addresses under hdev->lock. Release the lock before sending HCI commands. Clear the controller event filter before building the snapshot, and skip allocation and the second list traversal when there are no matching entries. This preserves the original filter and scan-state updates without retaining an accept-list node across a controller wait.
