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-2026-97979 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-2026-97979/ (Markdown: https://insights.sbomify.com/CVE-2026-97979/index.md)","id":"CVE-2026-97979","markdown":"https://insights.sbomify.com/CVE-2026-97979/index.md","name":"CVE-2026-97979","record":{"aliases":["AZL-104730","BELL-CVE-2026-97979","DEBIAN-CVE-2026-97979","GHSA-f354-573p-458p","UBUNTU-CVE-2026-97979"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A memory leak in the Linux kernel ice driver can lead to resource exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nice: add missing xa_destroy for sched_node_ids\n\nCommit 16dfa49406bc (\"ice: Introduce new parameters in ice_sched_node\")\nadded a sched_node_ids xarray to the port info structure, but never called\nxa_destroy on it.\n\nSince xarrays can allocate internal memory, this can result in a memory\nleak even if every element in the xarray has been removed.\n\nThe xarray is currently embedded in the port_info structure. This appears\nto have been done because its use is within functions that take the\nport_info as a primary argument.\n\nHowever, this complicates managing the lifecycle of the field. The\nport_info structure is allocated in ice_init_hw() using devm, and it is\nnot released until the devm cleanup when the driver is unloaded.\n\nThe ice_init_hw() function is called in many places, including devlink\nreload, and possibly during DDP load after updating the Tx scheduler\nlayout.\n\nAdding a call of xa_destroy to the ice_deinit_hw() causes Sashiko to raise\nmultiple concerns due to potential ordering issues and possible ways that\nport_info could be a dangling reference.\n\nTo handle this, move the sched_node_ids out of port_info and into the hw\nstructure. All users of the array already have a pointer to hw anyways, and\nthere is only one sched_node_ids per adapter. While here, remove the overly\nverbose comment explaining the nature of the sched_node_ids xarray.\n\nAdd the missing xa_destroy to the cleanup path and to ice_deinit_hw(),\nensuring that we properly release the xarray memory.\n\nThis was caught by Sashiko during development of unrelated code.","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":"ice: add missing xa_destroy for sched_node_ids","id":"CVE-2026-97979","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"s390/debug: Fix NULL pointer dereference in debug_set_level()","id":"CVE-2026-97980"},"packages":[],"prev":{"headline":"eth: ice: don't dereference pointers from TP_printk()","id":"CVE-2026-97978"},"products":["Linux"],"published":"2026-09-25","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A memory leak in the Linux kernel ice driver can lead to resource exhaustion and denial of service.","url":"https://insights.sbomify.com/CVE-2026-97979/"}
