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-2026-80997 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-2026-80997/ (Markdown: https://insights.sbomify.com/CVE-2026-80997/index.md)","id":"CVE-2026-80997","markdown":"https://insights.sbomify.com/CVE-2026-80997/index.md","name":"CVE-2026-80997","record":{"aliases":["BELL-CVE-2026-80997","DEBIAN-CVE-2026-80997","GHSA-4hqp-w86v-96hh","UBUNTU-CVE-2026-80997"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A race condition in the Linux kernel IPA driver causes permanent network transmit stalls after runtime resume, 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\nnet: ipa: fix stalled modem TX queue after runtime resume\n\nipa_start_xmit() unconditionally stops the TX queue before calling\npm_runtime_get(), relying on the wake scheduled by runtime resume\n(ipa_modem_wake_queue_work()) to restart it once power is ACTIVE.\nBut that work is queued from within the runtime resume callback,\nbefore the device's power state reaches RPM_ACTIVE, so it can run\nwhile the device is still RPM_RESUMING.  The wake is then consumed\ntoo early: the transmit it restarts stops the queue again,\npm_runtime_get() returns -EINPROGRESS without arranging any future\nwake (deferred_resume exists only for RPM_SUSPENDING), and after the\nresume completes nothing is left to wake the queue.  Transmit stalls\npermanently: packets pile up in the qdisc behind the stopped queue,\nthe device runtime-suspends, and since the netdev registers no\nndo_tx_timeout the watchdog never fires.  Observed on SM7635\n(Fairphone 6) as the cellular data path going permanently deaf\nwithin hours, RX included, since nothing resumes the suspended\nendpoints.\n\nClose the window by making the wake work wait for the resume to\ncomplete (pm_runtime_get_sync()) before waking the queue.  Every\nqueue stop is then guaranteed a later wake that happens while power\nis ACTIVE; a transmit racing a new suspend/resume cycle re-schedules\nthe work.  If the device could not be resumed, wake the queue anyway\nso pending packets are dropped by the transmit path rather than\nstranded.\n\nThe STARTED power flag used to narrow this window: a wake running\nbefore the transmit path's stop suppressed that stop, but only once,\nas the flag was cleared by the first stop it absorbed.  Removing the\nflag made a single transmit during an in-flight resume sufficient to\nstrand the queue, which is the form observed.\n\nWith an accelerated reproducer (autosuspend delay shortened to 5 ms,\n~20 packets/s of TX), an unpatched kernel stalled three times in\n230 s / 4380 packets; with this patch the same test ran 3601 s /\n70298 packets without a stall.","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":"net: ipa: fix stalled modem TX queue after runtime resume","id":"CVE-2026-80997","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"net: bnxt: ring the doorbell when SW USO exits early","id":"CVE-2026-80998"},"packages":[],"prev":{"headline":"net: l2tp: do not propagate multicast notification errors","id":"CVE-2026-80996"},"products":["Linux"],"published":"2026-09-11","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":"2026-10-19","vendors":["Linux"]},"summary":"A race condition in the Linux kernel IPA driver causes permanent network transmit stalls after runtime resume, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2026-80997/"}
