CVE-2026-46015: Software Security Vulnerability Vulnerability
HIGHCVE-2026-46015 is a HIGH (CVSS 7.8) security vulnerability vulnerability (CWE-408: Incorrect Behavior Order: Early Amplification) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product allows an entity to perform a legitimate but expensive operation before authentication or authorization has taken place.. Remediation is available in the latest vendor maintenance releases.
CVE-2026-46015 at a Glance
Security Impact
CVSS: 7.8
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2026-46015
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.
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:treeHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-46015, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:treeAnalyze 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.

"details" : "In the Linux kernel, the following vulnerability has been resolved:\n\ntcp: call sk_data_ready() after listener migration\n\nWhen inet_csk_listen_stop() migrates an established child socket from\na closing listener to another socket in the same SO_REUSEPORT group,\nthe target listener gets a new accept-queue entry via\ninet_csk_reqsk_queue_add(), but that path never notifies the target\nlistener's waiters. A nonblocking accept() still works because it\nchecks the queue directly, but poll()/epoll_wait() waiters and\nblocking accept() callers can also remain asleep indefinitely.\n\nCall READ_ONCE(nsk->sk_data_ready)(nsk) after a successful migration\nin inet_csk_listen_stop().\n\nHowever, after inet_csk_reqsk_queue_add() succeeds, the ref acquired\nin reuseport_migrate_sock() is effectively transferred to\nnreq->rsk_listener. Another CPU can then dequeue nreq via accept()\nor listener shutdown, hit reqsk_put(), and drop that listener ref.\nSince listeners are SOCK_RCU_FREE, wrap the post-queue_add()\ndereferences of nsk in rcu_read_lock()/rcu_read_unlock(), which also\ncovers the existing sock_net(nsk) access in that path.\n\nThe reqsk_timer_handler() path does not need the same changes for two\nreasons: half-open requests become readable only after the final ACK,\nwhere tcp_child_process() already wakes the listener; and once nreq is\nvisible via inet_ehash_insert(), the success path no longer touches\nnsk directly.",
