The issue arises from incorrect handling of the netdev reference count, where the `dev_tracker` associated with the AX.25 device is improperly managed. Specifically, the `dev_tracker` of the `ax25_cb` should be deallocated during device detachment in the `ax25_kill_by_device()` function, but it was mistakenly tied to the `ax25_dev`. This mismanagement leads to a reference count mismatch, triggering warnings and potential system instability, as indicated by logs showing already released references."], "mitigation": {"lang": "en:us", "value": "Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability."}, "name": "CVE-2024-36009", "package_state": [{"cpe": "cpe:/o:redhat:enterprise_linux:6", "fix_state": "Not affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 6"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Not affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Not affected", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Not affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Not affected", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Not affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 9"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Not affected", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 9"}], "public_date": "2024-05-20T00:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2024-36009\nhttps://nvd.nist.gov/vuln/detail/CVE-2024-36009\nhttps://lore.kernel.org/linux-cve-announce/2024052026-CVE-2024-36009-f213@gregkh/T"], "statement": "Red Hat Enterprise Linux is not vulnerable to this CVE, as it does not affect the versions or configurations of the Linux kernel used in its distributions.", "threat_severity": "Moderate"}
