But it ended up adding a leak of its own. When\nskb_orphan_frags_rx() fails, the function just returns, leaking the skb\nit just cloned. Free it before returning.\n\nThis bug was discovered and resolved using Coverity Static Analysis\nSecurity Testing (SAST) by Synopsys, Inc.","modified":"2026-03-20T12:33:18.773241Z","published":"2025-10-22T13:23:49.536Z","related":["SUSE-SU-2025:4149-1","SUSE-SU-2025:4320-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53716.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/58766252f6b2c0487cda6976a53d2bb03ae28e2a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/779332447108545ef04682ea29af5f85c0202aee"},{"type":"WEB","url":"https://git.kernel.org/stable/c/82501f1ead557cbee1c2467654ec109a80334d22"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8a02fb71d7192ff1a9a47c9d937624966c6e09af"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a594382ec6d0cc8cff5a8bc7e61b54e3858fb243"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cc18b4685910d5d9de8314bae9c55790701b1811"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e06841a2abf9c82735cee39e88b1d79464088840"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f4d928c00254cfc9dd0ee7076f4a59bceec675f4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53716.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53716"},{"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":"281072fb2a7294cde7acbf5375b879f40a8001b7"},{"fixed":"82501f1ead557cbee1c2467654ec109a80334d22"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"1f69c086b20e27763af28145981435423f088268"},{"fixed":"779332447108545ef04682ea29af5f85c0202aee"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"602fa8af44fd55a58f9e94eb673e8adad2c6cc46"},{"fixed":"58766252f6b2c0487cda6976a53d2bb03ae28e2a"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"230a5ed7d813fb516de81d23f09d7506753e41e9"},{"fixed":"a594382ec6d0cc8cff5a8bc7e61b54e3858fb243"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"43e4197dd5f6b474a8b16f8b6a42cd45cf4f9d1a"},{"fixed":"e06841a2abf9c82735cee39e88b1d79464088840"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"cb52e7f24c1d01a536a847dff0d1d95889cc3b5c"},{"fixed":"cc18b4685910d5d9de8314bae9c55790701b1811"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"426384dd4980040651536fef5feac4dcc4d7ee4e"},{"fixed":"f4d928c00254cfc9dd0ee7076f4a59bceec675f4"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"50749f2dd6854a41830996ad302aef2ffaf011d8"},{"fixed":"8a02fb71d7192ff1a9a47c9d937624966c6e09af"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"30290f210ba7426ff7592fe2eb4114b1b5bad219"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-53716.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.14.315"},{"fixed":"4.14.316"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.19.283"},{"fixed":"4.19.284"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.4.243"},{"fixed":"5.4.244"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.10.180"},{"fixed":"5.10.181"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.15.111"},{"fixed":"5.15.114"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.1.28"},{"fixed":"6.1.31"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.3.2"},{"fixed":"6.3.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-53716.json"}}],"schema_version":"1.7.5"}
