{"id":"CVE-2026-97440","summary":"net: qrtr: fix node refcount leak on ctrl packet alloc failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: qrtr: fix node refcount leak on ctrl packet alloc failure\n\nqrtr_send_resume_tx() calls qrtr_node_lookup() which takes a\nreference on the returned node. If the subsequent call to\nqrtr_alloc_ctrl_packet() fails due to memory allocation failure, the\nfunction returns -ENOMEM without calling qrtr_node_release() to\nrelease the node reference.\n\nAdd qrtr_node_release(node) before returning on the allocation failure\npath to properly release the reference.","modified":"2026-10-22T10:35:10.315225260Z","published":"2026-09-24T16:03:53.360Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97440.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3b09ff54114566864eea59020f6b69c5bb325b9d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/477353db343663d5502ca442c6de785d2f23f273"},{"type":"WEB","url":"https://git.kernel.org/stable/c/78d066ecac9ce50441d4affae0df2093c4c3e62e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9d969c98732a4d42212ec580dd5bbad53f246103"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c3515740174b778d0ee44acc477b51a6478da6b8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f3e90fbcd2d5ec1632bc2e8cdd1218f56bcb5fcf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f76a39c45182d9137e053081cee9f2c197404ce6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97440.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97440"},{"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":"cb6530b99fafea6c0636c4640bd21301d12cdbc9"},{"fixed":"78d066ecac9ce50441d4affae0df2093c4c3e62e"},{"fixed":"f3e90fbcd2d5ec1632bc2e8cdd1218f56bcb5fcf"},{"fixed":"c3515740174b778d0ee44acc477b51a6478da6b8"},{"fixed":"f76a39c45182d9137e053081cee9f2c197404ce6"},{"fixed":"477353db343663d5502ca442c6de785d2f23f273"},{"fixed":"9d969c98732a4d42212ec580dd5bbad53f246103"},{"fixed":"3b09ff54114566864eea59020f6b69c5bb325b9d"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-97440.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.6.0"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-97440.json"}}],"schema_version":"1.9.2"}
