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-2025-37743 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-2025-37743/ (Markdown: https://insights.sbomify.com/CVE-2025-37743/index.md)","id":"CVE-2025-37743","markdown":"https://insights.sbomify.com/CVE-2025-37743/index.md","name":"CVE-2025-37743","record":{"aliases":["BELL-CVE-2025-37743","DEBIAN-CVE-2025-37743","GHSA-v99v-6wp3-34rf","ROOT-OS-DEBIAN-13-CVE-2025-37743","ROOT-OS-UBUNTU-2204-CVE-2025-37743","ROOT-OS-UBUNTU-2404-CVE-2025-37743","UBUNTU-CVE-2025-37743"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel WiFi driver","requires_auth":"low_privilege","summary":"A memory leak in the ath12k WiFi driver can lead to resource exhaustion and denial of service when extended statistics mode is enabled.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath12k: Avoid memory leak while enabling statistics\n\nDriver uses monitor destination rings for extended statistics mode and\nstandalone monitor mode. In extended statistics mode, TLVs are parsed from\nthe buffer received from the monitor destination ring and assigned to the\nppdu_info structure to update per-packet statistics. In standalone monitor\nmode, along with per-packet statistics, the packet data (payload) is\ncaptured, and the driver updates per MSDU to mac80211.\n\nWhen the AP interface is enabled, only extended statistics mode is\nactivated. As part of enabling monitor rings for collecting statistics,\nthe driver subscribes to HAL_RX_MPDU_START TLV in the filter\nconfiguration. This TLV is received from the monitor destination ring, and\nkzalloc for the mon_mpdu object occurs, which is not freed, leading to a\nmemory leak. The kzalloc for the mon_mpdu object is only required while\nenabling the standalone monitor interface. This causes a memory leak while\nenabling extended statistics mode in the driver.\n\nFix this memory leak by removing the kzalloc for the mon_mpdu object in\nthe HAL_RX_MPDU_START TLV handling. Additionally, remove the standalone\nmonitor mode handlings in the HAL_MON_BUF_ADDR and HAL_RX_MSDU_END TLVs.\nThese TLV tags will be handled properly when enabling standalone monitor\nmode in the future.\n\nTested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1\nTested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3","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: ath12k: Avoid memory leak while enabling statistics","id":"CVE-2025-37743","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":4,"next":{"headline":"wifi: ath12k: fix memory leak in ath12k_pci_remove()","id":"CVE-2025-37744"},"packages":[],"prev":{"headline":"jfs: Fix uninit-value access of imap allocated in the diMount() function","id":"CVE-2025-37742"},"products":["Linux"],"published":"2025-05-01","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-21","vendors":["Linux"]},"summary":"A memory leak in the ath12k WiFi driver can lead to resource exhaustion and denial of service when extended statistics mode is enabled.","url":"https://insights.sbomify.com/CVE-2025-37743/"}
