{"id":"CVE-2026-98633","summary":"Bluetooth: btnxpuart: Fix skb leak in nxp_process_fw_dump()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: btnxpuart: Fix skb leak in nxp_process_fw_dump()\n\nWhen CONFIG_DEV_COREDUMP=n, hci_devcd_append() returns -EOPNOTSUPP\nwithout freeing its skb argument. This leaks the cloned skb and also\nprevents nxp_set_ind_reset() from being called to perform recovery.\n\nFix by guarding the hci_devcd_append(hdev, skb_clone(skb, GFP_ATOMIC))\ncall with IS_ENABLED(CONFIG_DEV_COREDUMP).","modified":"2026-10-20T02:30:31.823594677Z","published":"2026-10-18T15:19:58.365Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98633.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8a36598050cd1e5abb1d5ed42cc224cfcb538c4f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/edcb84ee607a9ddfc6f2771a7f399115f0b0f19d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f2bbb36426581045a8bf7793da5419b9375e4348"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98633.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98633"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"998e447f443f138c90faa6ff3845082af419070e"},{"fixed":"8a36598050cd1e5abb1d5ed42cc224cfcb538c4f"},{"fixed":"edcb84ee607a9ddfc6f2771a7f399115f0b0f19d"},{"fixed":"f2bbb36426581045a8bf7793da5419b9375e4348"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98633.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.15.0"},{"fixed":"6.18.55"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98633.json"}}],"schema_version":"1.9.0"}
