An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-38379 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-2025-38379/ (Markdown: https://insights.sbomify.com/CVE-2025-38379/index.md)","id":"CVE-2025-38379","markdown":"https://insights.sbomify.com/CVE-2025-38379/index.md","name":"CVE-2025-38379","record":{"aliases":["AZL-65780","BELL-CVE-2025-38379","DEBIAN-CVE-2025-38379","GHSA-mj73-cg42-f79h","UBUNTU-CVE-2025-38379"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel SMB client","requires_auth":"none","summary":"A null pointer dereference in the Linux kernel SMB client during channel reconnection can cause a system crash.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: fix warning when reconnecting channel\n\nWhen reconnecting a channel in smb2_reconnect_server(), a dummy tcon\nis passed down to smb2_reconnect() with -\u003equery_interface\nuninitialized, so we can't call queue_delayed_work() on it.\n\nFix the following warning by ensuring that we're queueing the delayed\nworker from correct tcon.\n\nWARNING: CPU: 4 PID: 1126 at kernel/workqueue.c:2498 __queue_delayed_work+0x1d2/0x200\nModules linked in: cifs cifs_arc4 nls_ucs2_utils cifs_md4 [last unloaded: cifs]\nCPU: 4 UID: 0 PID: 1126 Comm: kworker/4:0 Not tainted 6.16.0-rc3 #5 PREEMPT(voluntary)\nHardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-4.fc42 04/01/2014\nWorkqueue: cifsiod smb2_reconnect_server [cifs]\nRIP: 0010:__queue_delayed_work+0x1d2/0x200\nCode: 41 5e 41 5f e9 7f ee ff ff 90 0f 0b 90 e9 5d ff ff ff bf 02 00\n00 00 e8 6c f3 07 00 89 c3 eb bd 90 0f 0b 90 e9 57 f\u003e 0b 90 e9 65 fe\nff ff 90 0f 0b 90 e9 72 fe ff ff 90 0f 0b 90 e9\nRSP: 0018:ffffc900014afad8 EFLAGS: 00010003\nRAX: 0000000000000000 RBX: ffff888124d99988 RCX: ffffffff81399cc1\nRDX: dffffc0000000000 RSI: ffff888114326e00 RDI: ffff888124d999f0\nRBP: 000000000000ea60 R08: 0000000000000001 R09: ffffed10249b3331\nR10: ffff888124d9998f R11: 0000000000000004 R12: 0000000000000040\nR13: ffff888114326e00 R14: ffff888124d999d8 R15: ffff888114939020\nFS:  0000000000000000(0000) GS:ffff88829f7fe000(0000) knlGS:0000000000000000\nCS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 00007ffe7a2b4038 CR3: 0000000120a6f000 CR4: 0000000000750ef0\nPKRU: 55555554\nCall Trace:\n \u003cTASK\u003e\n queue_delayed_work_on+0xb4/0xc0\n smb2_reconnect+0xb22/0xf50 [cifs]\n smb2_reconnect_server+0x413/0xd40 [cifs]\n ?
