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-2025-68320 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2025-68320/ (Markdown: https://insights.sbomify.com/CVE-2025-68320/index.md)","id":"CVE-2025-68320","markdown":"https://insights.sbomify.com/CVE-2025-68320/index.md","name":"CVE-2025-68320","record":{"aliases":["BELL-CVE-2025-68320","DEBIAN-CVE-2025-68320","GHSA-f4gj-826g-pqfv","ROOT-OS-DEBIAN-12-CVE-2025-68320","ROOT-OS-DEBIAN-13-CVE-2025-68320","ROOT-OS-UBUNTU-2404-CVE-2025-68320","UBUNTU-CVE-2025-68320"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A bug in the lan966x network driver causes a kernel warning and potential instability when reading stats, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"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\nlan966x: Fix sleeping in atomic context\n\nThe following warning was seen when we try to connect using ssh to the device.\n\nBUG: sleeping function called from invalid context at kernel/locking/mutex.c:575\nin_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 104, name: dropbear\npreempt_count: 1, expected: 0\nINFO: lockdep is turned off.\nCPU: 0 UID: 0 PID: 104 Comm: dropbear Tainted: G        W           6.18.0-rc2-00399-g6f1ab1b109b9-dirty #530 NONE\nTainted: [W]=WARN\nHardware name: Generic DT based system\nCall trace:\n unwind_backtrace from show_stack+0x10/0x14\n show_stack from dump_stack_lvl+0x7c/0xac\n dump_stack_lvl from __might_resched+0x16c/0x2b0\n __might_resched from __mutex_lock+0x64/0xd34\n __mutex_lock from mutex_lock_nested+0x1c/0x24\n mutex_lock_nested from lan966x_stats_get+0x5c/0x558\n lan966x_stats_get from dev_get_stats+0x40/0x43c\n dev_get_stats from dev_seq_printf_stats+0x3c/0x184\n dev_seq_printf_stats from dev_seq_show+0x10/0x30\n dev_seq_show from seq_read_iter+0x350/0x4ec\n seq_read_iter from seq_read+0xfc/0x194\n seq_read from proc_reg_read+0xac/0x100\n proc_reg_read from vfs_read+0xb0/0x2b0\n vfs_read from ksys_read+0x6c/0xec\n ksys_read from ret_fast_syscall+0x0/0x1c\nException stack(0xf0b11fa8 to 0xf0b11ff0)\n1fa0:                   00000001 00001000 00000008 be9048d8 00001000 00000001\n1fc0: 00000001 00001000 00000008 00000003 be905920 0000001e 00000000 00000001\n1fe0: 0005404c be9048c0 00018684 b6ec2cd8\n\nIt seems that we are using a mutex in a atomic context which is wrong.\nChange the mutex with a spinlock.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"lan966x: Fix sleeping in atomic context","id":"CVE-2025-68320","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":4,"next":{"headline":"page_pool: always add GFP_NOWARN for ATOMIC allocations","id":"CVE-2025-68321"},"packages":[],"prev":{"headline":"netconsole: Acquire su_mutex before navigating configs hierarchy","id":"CVE-2025-68319"},"products":["Linux"],"published":"2025-12-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A bug in the lan966x network driver causes a kernel warning and potential instability when reading stats, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2025-68320/"}
