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-2026-74429 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-2026-74429/ (Markdown: https://insights.sbomify.com/CVE-2026-74429/index.md)","id":"CVE-2026-74429","markdown":"https://insights.sbomify.com/CVE-2026-74429/index.md","name":"CVE-2026-74429","record":{"aliases":["BELL-CVE-2026-74429","DEBIAN-CVE-2026-74429","GHSA-p3f2-6553-5mwv","UBUNTU-CVE-2026-74429"],"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 null pointer dereference in the Linux kernel's rxrpc module can cause a system crash when a reply packet is received before data transmission.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\nrxrpc: Fix the reception of a reply packet before data transmission\n\nFix rxrpc_receiving_reply() to handle the reception of an apparent reply\nDATA packet before rxrpc has had a chance to send any request DATA packets\non a client call by checking to see if the call has been exposed yet by\nsending the first packet.\n\nWithout this, rxrpc_rotate_tx_window() might oops.\n\nAlso fix rxrpc_rotate_tx_window() to handle the Tx queue being empty by\nchanging the do...while loop into a while loop, just in case a call is\nabnormally terminated by an early reply before the last request packet is\ntransmitted.","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":"rxrpc: Fix the reception of a reply packet before data transmission","id":"CVE-2026-74429","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"rxrpc: Fix ACKALL packet handling","id":"CVE-2026-74430"},"packages":[],"prev":{"headline":"rxrpc: Fix double unlock in rxrpc_recvmsg()","id":"CVE-2026-74428"},"products":["Linux"],"published":"2026-08-15","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":"2026-08-17","vendors":["Linux"]},"summary":"A null pointer dereference in the Linux kernel's rxrpc module can cause a system crash when a reply packet is received before data transmission.","url":"https://insights.sbomify.com/CVE-2026-74429/"}
