It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-38150 in the wild and no public exploit code.\n\nAffected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-38150/ (Markdown: https://insights.sbomify.com/CVE-2025-38150/index.md)","id":"CVE-2025-38150","markdown":"https://insights.sbomify.com/CVE-2025-38150/index.md","name":"CVE-2025-38150","record":{"aliases":["BELL-CVE-2025-38150","GHSA-2x7p-gc2x-3v72","UBUNTU-CVE-2025-38150"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel's af_packet module can cause a sleeping function call in invalid context, leading to a system crash.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-667","name":"Improper Locking"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\naf_packet: move notifier's packet_dev_mc out of rcu critical section\n\nSyzkaller reports the following issue:\n\n BUG: sleeping function called from invalid context at kernel/locking/mutex.c:578\n __mutex_lock+0x106/0xe80 kernel/locking/mutex.c:746\n team_change_rx_flags+0x38/0x220 drivers/net/team/team_core.c:1781\n dev_change_rx_flags net/core/dev.c:9145 [inline]\n __dev_set_promiscuity+0x3f8/0x590 net/core/dev.c:9189\n netif_set_promiscuity+0x50/0xe0 net/core/dev.c:9201\n dev_set_promiscuity+0x126/0x260 net/core/dev_api.c:286 packet_dev_mc net/packet/af_packet.c:3698 [inline]\n packet_dev_mclist_delete net/packet/af_packet.c:3722 [inline]\n packet_notifier+0x292/0xa60 net/packet/af_packet.c:4247\n notifier_call_chain+0x1b3/0x3e0 kernel/notifier.c:85\n call_netdevice_notifiers_extack net/core/dev.c:2214 [inline]\n call_netdevice_notifiers net/core/dev.c:2228 [inline]\n unregister_netdevice_many_notify+0x15d8/0x2330 net/core/dev.c:11972\n rtnl_delete_link net/core/rtnetlink.c:3522 [inline]\n rtnl_dellink+0x488/0x710 net/core/rtnetlink.c:3564\n rtnetlink_rcv_msg+0x7cf/0xb70 net/core/rtnetlink.c:6955\n netlink_rcv_skb+0x219/0x490 net/netlink/af_netlink.c:2534\n\nCalling `PACKET_ADD_MEMBERSHIP` on an ops-locked device can trigger\nthe `NETDEV_UNREGISTER` notifier, which may require disabling promiscuous\nand/or allmulti mode.
