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-2022-49552 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-2022-49552/ (Markdown: https://insights.sbomify.com/CVE-2022-49552/index.md)","id":"CVE-2022-49552","markdown":"https://insights.sbomify.com/CVE-2022-49552/index.md","name":"CVE-2022-49552","record":{"aliases":["AZL-68687","DEBIAN-CVE-2022-49552","GHSA-hg9m-frc8-4qpx","ROOT-OS-UBUNTU-2204-CVE-2022-49552","UBUNTU-CVE-2022-49552"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A flaw in Linux kernel BPF JIT blinding allows attackers to trigger a page fault and potential code execution via crafted BPF programs.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/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\nbpf: Fix combination of jit blinding and pointers to bpf subprogs.\n\nThe combination of jit blinding and pointers to bpf subprogs causes:\n[   36.989548] BUG: unable to handle page fault for address: 0000000100000001\n[   36.990342] #PF: supervisor instruction fetch in kernel mode\n[   36.990968] #PF: error_code(0x0010) - not-present page\n[   36.994859] RIP: 0010:0x100000001\n[   36.995209] Code: Unable to access opcode bytes at RIP 0xffffffd7.\n[   37.004091] Call Trace:\n[   37.004351]  \u003cTASK\u003e\n[   37.004576]  ? bpf_loop+0x4d/0x70\n[   37.004932]  ? bpf_prog_3899083f75e4c5de_F+0xe3/0x13b\n\nThe jit blinding logic didn't recognize that ld_imm64 with an address\nof bpf subprogram is a special instruction and proceeded to randomize it.\nBy itself it wouldn't have been an issue, but jit_subprogs() logic\nrelies on two step process to JIT all subprogs and then JIT them\nagain when addresses of all subprogs are known.\nBlinding process in the first JIT phase caused second JIT to miss\nadjustment of special ld_imm64.\n\nFix this issue by ignoring special ld_imm64 instructions that don't have\nuser controlled constants and shouldn't be blinded.","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 combination of jit blinding and pointers to bpf subprogs.","id":"CVE-2022-49552","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":3,"next":{"headline":"fs/ntfs3: validate BOOT sectors_per_clusters","id":"CVE-2022-49553"},"packages":[],"prev":{"headline":"usb: isp1760: Fix out-of-bounds array access","id":"CVE-2022-49551"},"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A flaw in Linux kernel BPF JIT blinding allows attackers to trigger a page fault and potential code execution via crafted BPF programs.","url":"https://insights.sbomify.com/CVE-2022-49552/"}
