How to Fix CVE-2026-72441

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-2026-72441, 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: ieee802154: fix kernel-infoleak in dgram_recvmsg() KMSAN reported a kernel-infoleak in move_addr_to_user(): BUG: KMSAN: kernel-infoleak in instrument_copy_to_user include/linux/instrumented.h:131 [inline] BUG: KMSAN: kernel-infoleak in _inline_copy_to_user include/linux/uaccess.h:205 [inline] BUG: KMSAN: kernel-infoleak in _copy_to_user+0xcc/0x120 lib/usercopy.c:26 instrument_copy_to_user include/linux/instrumented.h:131 [inline] _inline_copy_to_user include/linux/uaccess.h:205 [inline] _copy_to_user+0xcc/0x120 lib/usercopy.c:26 copy_to_user include/linux/uaccess.h:236 [inline] move_addr_to_user+0x2e7/0x440 net/socket.c:302 ____sys_recvmsg+0x232/0x610 net/socket.c:2925 ... Uninit was stored to memory at: ieee802154_addr_to_sa include/net/ieee802154_netdev.h:369 [inline] dgram_recvmsg+0xa09/0xbe0 net/ieee802154/socket.c:739 The issue occurs because the `pan_id` field of `struct ieee802154_addr` is left uninitialized when the address mode is `IEEE802154_ADDR_NONE`. The execution flow is as follows: 1. `__ieee802154_rx_handle_packet()` declares a local `struct ieee802154_hdr hdr` on the stack. 2. `ieee802154_hdr_pull()` calls `ieee802154_hdr_get_addr()` to parse the source and destination addresses into this structure. 3. If the address mode is `IEEE802154_ADDR_NONE`, `ieee802154_hdr_get_addr()` previously only set the `mode` field, leaving the `pan_id` field containing uninitialized stack memory. 4. This uninitialized `pan_id` is later copied into a `struct sockaddr_ieee802154` in `dgram_recvmsg()` via `ieee802154_addr_to_sa()`. 5. Finally, `move_addr_to_user()` copies the socket address structure to user space, leaking the uninitialized bytes. Fix this by using `memset` to zero out the address structure in `ieee802154_hdr_get_addr()` when the mode is `IEEE802154_ADDR_NONE`.
