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-2023-52597 in the wild and no public exploit code.\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-2023-52597/ (Markdown: https://insights.sbomify.com/CVE-2023-52597/index.md)","id":"CVE-2023-52597","markdown":"https://insights.sbomify.com/CVE-2023-52597/index.md","name":"CVE-2023-52597","record":{"aliases":["BELL-CVE-2023-52597","DEBIAN-CVE-2023-52597","GHSA-6j3q-64jm-q33g","UBUNTU-CVE-2023-52597"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel KVM","requires_auth":"none","summary":"A race condition in KVM s390 allows host process corruption, potentially enabling privilege escalation or code execution on the host.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: s390: fix setting of fpc register\n\nkvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point control\n(fpc) register of a guest cpu. The new value is tested for validity by\ntemporarily loading it into the fpc register.\n\nThis may lead to corruption of the fpc register of the host process:\nif an interrupt happens while the value is temporarily loaded into the fpc\nregister, and within interrupt context floating point or vector registers\nare used, the current fp/vx registers are saved with save_fpu_regs()\nassuming they belong to user space and will be loaded into fp/vx registers\nwhen returning to user space.\n\ntest_fp_ctl() restores the original user space / host process fpc register\nvalue, however it will be discarded, when returning to user space.\n\nIn result the host process will incorrectly continue to run with the value\nthat was supposed to be used for a guest cpu.\n\nFix this by simply removing the test. There is another test right before\nthe SIE context is entered which will handles invalid values.\n\nThis results in a change of behaviour: invalid values will now be accepted\ninstead of that the ioctl fails with -EINVAL.
