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-2026-90417 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-2026-90417/ (Markdown: https://insights.sbomify.com/CVE-2026-90417/index.md)","id":"CVE-2026-90417","markdown":"https://insights.sbomify.com/CVE-2026-90417/index.md","name":"CVE-2026-90417","record":{"aliases":["AZL-102695","BELL-CVE-2026-90417","DEBIAN-CVE-2026-90417","GHSA-ccpx-w89w-v2mx","UBUNTU-CVE-2026-90417"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel RDMA driver","requires_auth":"none","summary":"A double free and memory leak in the Linux kernel's cxgb4 RDMA driver can lead to system crashes or potential code execution.","user_interaction":"not_required","vuln_class":"use_after_free"},"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\nRDMA/cxgb4: Fix dereg_skb leak and double free in write_tpt_entry()\n\nWhen the device is in the fatal error state, write_tpt_entry() returns -EIO\nbefore handing the caller's preallocated skb to the transmit path; its\nallocation-failure returns do the same. c4iw_dereg_mr() ignores the error\nand frees mhp, leaking mhp-\u003edereg_skb. c4iw_get_dma_mr() instead frees the\nskb a second time after dereg_mem() already consumed it, a double free.\n\nMake write_tpt_entry() the sole owner of a non-NULL skb, freeing it on\nevery return preceding handoff to c4iw_ofld_send(): fatal error, tpt and\nstag allocation failure. c4iw_ofld_send() consumes the skb on success and\nerror alike, so drop the redundant kfree_skb() in c4iw_get_dma_mr() after\ndereg_mem().","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":"RDMA/cxgb4: Fix dereg_skb leak and double free in write_tpt_entry()","id":"CVE-2026-90417","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"nilfs2: fix BUG in nilfs_copy_dirty_pages() on dirty state mismatch","id":"CVE-2026-90418"},"packages":[],"prev":{"headline":"RDMA/mlx5: Fix stack out-of-bounds read in cc_params debugfs","id":"CVE-2026-90416"},"products":["Linux"],"published":"2026-09-17","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":"2026-10-21","vendors":["Linux"]},"summary":"A double free and memory leak in the Linux kernel's cxgb4 RDMA driver can lead to system crashes or potential code execution.","url":"https://insights.sbomify.com/CVE-2026-90417/"}
