An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-52832 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-2023-52832/ (Markdown: https://insights.sbomify.com/CVE-2023-52832/index.md)","id":"CVE-2023-52832","markdown":"https://insights.sbomify.com/CVE-2023-52832/index.md","name":"CVE-2023-52832","record":{"aliases":["BELL-CVE-2023-52832","DEBIAN-CVE-2023-52832","GHSA-9hhf-j948-m466","UBUNTU-CVE-2023-52832"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel Wi-Fi","requires_auth":"none","summary":"A signed integer overflow in the Linux kernel Wi-Fi subsystem can cause a UBSAN warning and potential system instability when retrieving unset power levels.","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":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-920","name":"Improper Restriction of Power Consumption"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: don't return unset power in ieee80211_get_tx_power()\n\nWe can get a UBSAN warning if ieee80211_get_tx_power() returns the\nINT_MIN value mac80211 internally uses for \"unset power level\".\n\n UBSAN: signed-integer-overflow in net/wireless/nl80211.c:3816:5\n -2147483648 * 100 cannot be represented in type 'int'\n CPU: 0 PID: 20433 Comm: insmod Tainted: G        WC OE\n Call Trace:\n  dump_stack+0x74/0x92\n  ubsan_epilogue+0x9/0x50\n  handle_overflow+0x8d/0xd0\n  __ubsan_handle_mul_overflow+0xe/0x10\n  nl80211_send_iface+0x688/0x6b0 [cfg80211]\n  [...]\n  cfg80211_register_wdev+0x78/0xb0 [cfg80211]\n  cfg80211_netdev_notifier_call+0x200/0x620 [cfg80211]\n  [...]\n  ieee80211_if_add+0x60e/0x8f0 [mac80211]\n  ieee80211_register_hw+0xda5/0x1170 [mac80211]\n\nIn this case, simply return an error instead, to indicate\nthat no data is available.","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":"wifi: mac80211: don't return unset power in ieee80211_get_tx_power()","id":"CVE-2023-52832","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"integer_overflow","year":"2023"},"n_packages":0,"n_references":6,"next":{"headline":"Bluetooth: btusb: Add date-\u003eevt_skb is NULL check","id":"CVE-2023-52833"},"packages":[],"prev":{"headline":"cpu/hotplug: Don't offline the last non-isolated CPU","id":"CVE-2023-52831"},"products":["Linux"],"published":"2024-05-21","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A signed integer overflow in the Linux kernel Wi-Fi subsystem can cause a UBSAN warning and potential system instability when retrieving unset power levels.","url":"https://insights.sbomify.com/CVE-2023-52832/"}
