{"id":"CVE-2026-72079","summary":"Input: ims-pcu - fix use-after-free and double-free in disconnect","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nInput: ims-pcu - fix use-after-free and double-free in disconnect\n\nims_pcu_disconnect() only intended to perform cleanup when the primary\n(control) interface is unbound. However, it currently relies on the\ninterface class to distinguish between control and data interfaces.\nA malicious device could present a data interface with the same class\nas the control interface, leading to premature cleanup and potential\nuse-after-free or double-free.\n\nSwitch to verifying that the interface being disconnected is indeed\nthe control interface.","modified":"2026-08-18T03:31:30.111695690Z","published":"2026-08-15T05:52:29.096Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72079.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/293388e42e5c0865204de6f36bfb8662156fce3b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/315f269ea04bc1477ab9bf351e939623d12a1621"},{"type":"WEB","url":"https://git.kernel.org/stable/c/462a999917755a3bf77448dfd64307963cf0a9f0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6a6c373e6a82eddc522342c8a8db7072c65f2b56"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6aacc18004b1a915ccb8a829d30279a37988066e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/921abbb33887052e46b1b77299f87a3c741dc580"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a4b3f4d42fbf58f06f0d49e37a9d0d9392eca338"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bf0b58ba489d0bdaa18c7dd8beeaeb954dd7dbb7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72079.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72079"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"628329d52474323938a03826941e166bc7c8eff4"},{"fixed":"315f269ea04bc1477ab9bf351e939623d12a1621"},{"fixed":"293388e42e5c0865204de6f36bfb8662156fce3b"},{"fixed":"921abbb33887052e46b1b77299f87a3c741dc580"},{"fixed":"6a6c373e6a82eddc522342c8a8db7072c65f2b56"},{"fixed":"a4b3f4d42fbf58f06f0d49e37a9d0d9392eca338"},{"fixed":"6aacc18004b1a915ccb8a829d30279a37988066e"},{"fixed":"bf0b58ba489d0bdaa18c7dd8beeaeb954dd7dbb7"},{"fixed":"462a999917755a3bf77448dfd64307963cf0a9f0"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72079.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.10.0"},{"fixed":"5.10.261"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.212"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72079.json"}}],"schema_version":"1.9.0"}
