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-2023-46841 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2023-46841/ (Markdown: https://insights.sbomify.com/CVE-2023-46841/index.md)","id":"CVE-2023-46841","markdown":"https://insights.sbomify.com/CVE-2023-46841/index.md","name":"CVE-2023-46841","record":{"aliases":["ALPINE-CVE-2023-46841","DEBIAN-CVE-2023-46841","GHSA-mxh6-2xpg-m77w","SUSE-SU-2024:0934-1","SUSE-SU-2024:0935-1","UBUNTU-CVE-2023-46841","openSUSE-SU-2024:13745-1"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Xen hypervisor","requires_auth":"low_privilege","summary":"Missing shadow stack cleanup during exception handling in Xen hypervisor can cause system crashes when CET is enabled.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"XEN","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"xen","vendor":"xen"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"Recent x86 CPUs offer functionality named Control-flow Enforcement\nTechnology (CET).  A sub-feature of this are Shadow Stacks (CET-SS).\nCET-SS is a hardware feature designed to protect against Return Oriented\nProgramming attacks. When enabled, traditional stacks holding both data\nand return addresses are accompanied by so called \"shadow stacks\",\nholding little more than return addresses.  Shadow stacks aren't\nwritable by normal instructions, and upon function returns their\ncontents are used to check for possible manipulation of a return address\ncoming from the traditional stack.\n\nIn particular certain memory accesses need intercepting by Xen.  In\nvarious cases the necessary emulation involves kind of replaying of\nthe instruction.  Such replaying typically involves filling and then\ninvoking of a stub.  Such a replayed instruction may raise an\nexceptions, which is expected and dealt with accordingly.\n\nUnfortunately the interaction of both of the above wasn't right:\nRecovery involves removal of a call frame from the (traditional) stack.\nThe counterpart of this operation for the shadow stack was missing.","ecosystems":["SUSE:Linux Enterprise Micro 5.1","SUSE:Linux Enterprise Micro 5.2","SUSE:Linux Enterprise Micro 5.3","SUSE:Linux Enterprise Micro 5.4","openSUSE:Leap Micro 5.3","openSUSE:Leap Micro 5.4","openSUSE:Tumbleweed"],"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":"x86: shadow stack vs exceptions from emulation stubs","id":"CVE-2023-46841","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fedoraproject:fedora","products":["fedoraproject:fedora","xen:xen"],"type":"other","year":"2023"},"n_packages":7,"n_references":2,"next":{"headline":"x86 HVM hypercalls may trigger Xen bug check","id":"CVE-2023-46842"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Micro 5.1","fixed":["4.14.6_12-150300.3.66.1"],"introduced":["0"],"last_affected":[],"package":"xen","purl":"pkg:rpm/suse/xen\u0026distro=SUSE%20Linux%20Enterprise%20Micro%205.1","source":"SUSE-SU-2024:0935-1"},{"ecosystem":"SUSE:Linux Enterprise Micro 5.2","fixed":["4.14.6_12-150300.3.66.1"],"introduced":["0"],"last_affected":[],"package":"xen","purl":"pkg:rpm/suse/xen\u0026distro=SUSE%20Linux%20Enterprise%20Micro%205.2","source":"SUSE-SU-2024:0935-1"},{"ecosystem":"SUSE:Linux Enterprise Micro 5.3","fixed":["4.16.5_14-150400.4.49.1"],"introduced":["0"],"last_affected":[],"package":"xen","purl":"pkg:rpm/suse/xen\u0026distro=SUSE%20Linux%20Enterprise%20Micro%205.3","source":"SUSE-SU-2024:0934-1"},{"ecosystem":"SUSE:Linux Enterprise Micro 5.4","fixed":["4.16.5_14-150400.4.49.1"],"introduced":["0"],"last_affected":[],"package":"xen","purl":"pkg:rpm/suse/xen\u0026distro=SUSE%20Linux%20Enterprise%20Micro%205.4","source":"SUSE-SU-2024:0934-1"},{"ecosystem":"openSUSE:Leap Micro 5.3","fixed":["4.16.5_14-150400.4.49.1"],"introduced":["0"],"last_affected":[],"package":"xen","purl":"pkg:rpm/opensuse/xen\u0026distro=openSUSE%20Leap%20Micro%205.3","source":"SUSE-SU-2024:0934-1"},{"ecosystem":"openSUSE:Leap Micro 5.4","fixed":["4.16.5_14-150400.4.49.1"],"introduced":["0"],"last_affected":[],"package":"xen","purl":"pkg:rpm/opensuse/xen\u0026distro=openSUSE%20Leap%20Micro%205.4","source":"SUSE-SU-2024:0934-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["4.18.0_06-2.1"],"introduced":["0"],"last_affected":[],"package":"xen","purl":"pkg:rpm/opensuse/xen\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:13745-1"}],"prev":{"headline":"VT-d: Failure to quarantine devices in !HVM builds","id":"CVE-2023-46840"},"products":["Xen"],"published":"2024-03-20","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"SUSE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-04","vendors":["Xen"]},"summary":"Missing shadow stack cleanup during exception handling in Xen hypervisor can cause system crashes when CET is enabled.","url":"https://insights.sbomify.com/CVE-2023-46841/"}
