It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-0045 exists.\n\nAffected product: Debian Debian 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-2023-0045/ (Markdown: https://insights.sbomify.com/CVE-2023-0045/index.md)","id":"CVE-2023-0045","markdown":"https://insights.sbomify.com/CVE-2023-0045/index.md","name":"CVE-2023-0045","record":{"aliases":["DEBIAN-CVE-2023-0045","GHSA-9x5g-vmxf-4qj8","UBUNTU-CVE-2023-0045"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux Kernel","requires_auth":"low_privilege","summary":"Attackers can bypass Spectre mitigations by exploiting a timing gap in the prctl syscall, potentially reading sensitive memory.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"},{"product":"active_iq_unified_manager","vendor":"netapp"},{"product":"h300s_firmware","vendor":"netapp"},{"product":"h410c_firmware","vendor":"netapp"},{"product":"h410s_firmware","vendor":"netapp"},{"product":"h500s_firmware","vendor":"netapp"},{"product":"h700s_firmware","vendor":"netapp"}],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-610","name":"Externally Controlled Reference to a Resource in Another Sphere"}],"description":"The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The ib_prctl_set  function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to the prctl syscall.  The patch that added the support for the conditional mitigation via prctl (ib_prctl_set) dates back to the kernel 4.9.176.\n\nWe recommend upgrading past commit a664ec9158eeddd75121d39c9a0758016097fa96","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-02-04","github_poc":2,"max_poc_stars":14,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-02-07T19:12:41Z","kind":"github_poc","ref":"https://github.com/es0j/CVE-2023-0045","stars":14,"title":null},{"date":"2023-02-04T22:42:21Z","kind":"github_poc","ref":"https://github.com/ASkyeye/CVE-2023-0045","stars":3,"title":null}],"tier":"weaponised"},"has_fix":true,"headline":"Incorrect indirect branch prediction barrier in the Linux Kernel","id":"CVE-2023-0045","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","linux:linux_kernel","netapp:active_iq_unified_manager","netapp:h300s_firmware","netapp:h410c_firmware","netapp:h410s_firmware","netapp:h500s_firmware","netapp:h700s_firmware"],"type":"security_feature_bypass","year":"2023"},"n_packages":0,"n_references":5,"next":{"headline":"Improper Restriction of Names for Files and Other Resources in lirantal/daloradius","id":"CVE-2023-0046"},"packages":[],"prev":{"headline":"Cross-site Scripting in Quarkus","id":"CVE-2023-0044"},"products":["Linux Kernel"],"published":"2023-04-25","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["Linux"]},"summary":"Attackers can bypass Spectre mitigations by exploiting a timing gap in the prctl syscall, potentially reading sensitive memory.","url":"https://insights.sbomify.com/CVE-2023-0045/"}
