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-2022-49548 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2022-49548/ (Markdown: https://insights.sbomify.com/CVE-2022-49548/index.md)","id":"CVE-2022-49548","markdown":"https://insights.sbomify.com/CVE-2022-49548/index.md","name":"CVE-2022-49548","record":{"aliases":["DEBIAN-CVE-2022-49548","GHSA-v45j-q282-89r5","UBUNTU-CVE-2022-49548"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A logic error in the Linux kernel BPF trampoline allows array overflow, potentially enabling local attackers to execute arbitrary code or escalate privileges.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-129","name":"Improper Validation of Array Index"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Fix potential array overflow in bpf_trampoline_get_progs()\n\nThe cnt value in the 'cnt \u003e= BPF_MAX_TRAMP_PROGS' check does not\ninclude BPF_TRAMP_MODIFY_RETURN bpf programs, so the number of\nthe attached BPF_TRAMP_MODIFY_RETURN bpf programs in a trampoline\ncan exceed BPF_MAX_TRAMP_PROGS.\n\nWhen this happens, the assignment '*progs++ = aux-\u003eprog' in\nbpf_trampoline_get_progs() will cause progs array overflow as the\nprogs field in the bpf_tramp_progs struct can only hold at most\nBPF_MAX_TRAMP_PROGS bpf programs.","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":"bpf: Fix potential array overflow in bpf_trampoline_get_progs()","id":"CVE-2022-49548","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"integer_overflow","year":"2022"},"n_packages":0,"n_references":5,"next":{"headline":"x86/MCE/AMD: Fix memory leak when threshold_create_bank() fails","id":"CVE-2022-49549"},"packages":[],"prev":{"headline":"btrfs: fix deadlock between concurrent dio writes when low on free data space","id":"CVE-2022-49547"},"products":["Linux"],"published":"2025-02-26","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A logic error in the Linux kernel BPF trampoline allows array overflow, potentially enabling local attackers to execute arbitrary code or escalate privileges.","url":"https://insights.sbomify.com/CVE-2022-49548/"}
