{"id":"CVE-2024-26715","summary":"usb: dwc3: gadget: Fix NULL pointer dereference in dwc3_gadget_suspend","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: dwc3: gadget: Fix NULL pointer dereference in dwc3_gadget_suspend\n\nIn current scenario if Plug-out and Plug-In performed continuously\nthere could be a chance while checking for dwc-\u003egadget_driver in\ndwc3_gadget_suspend, a NULL pointer dereference may occur.\n\nCall Stack:\n\n\tCPU1:                           CPU2:\n\tgadget_unbind_driver            dwc3_suspend_common\n\tdwc3_gadget_stop                dwc3_gadget_suspend\n                                        dwc3_disconnect_gadget\n\nCPU1 basically clears the variable and CPU2 checks the variable.\nConsider CPU1 is running and right before gadget_driver is cleared\nand in parallel CPU2 executes dwc3_gadget_suspend where it finds\ndwc-\u003egadget_driver which is not NULL and resumes execution and then\nCPU1 completes execution. CPU2 executes dwc3_disconnect_gadget where\nit checks dwc-\u003egadget_driver is already NULL because of which the\nNULL pointer deference occur.","modified":"2026-04-02T10:05:39.743199Z","published":"2024-04-03T14:55:16.395Z","related":["SUSE-SU-2024:2008-1","SUSE-SU-2024:2019-1","SUSE-SU-2024:2190-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/26xxx/CVE-2024-26715.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/36695d5eeeefe5a64b47d0336e7c8fc144e78182"},{"type":"WEB","url":"https://git.kernel.org/stable/c/57e2e42ccd3cd6183228269715ed032f44536751"},{"type":"WEB","url":"https://git.kernel.org/stable/c/61a348857e869432e6a920ad8ea9132e8d44c316"},{"type":"WEB","url":"https://git.kernel.org/stable/c/88936ceab6b426f1312327e9ef849c215c6007a7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c7ebd8149ee519d27232e6e4940e9c02071b568b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/26xxx/CVE-2024-26715.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-26715"},{"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":"9772b47a4c2916d645c551228b6085ea24acbe5d"},{"fixed":"88936ceab6b426f1312327e9ef849c215c6007a7"},{"fixed":"57e2e42ccd3cd6183228269715ed032f44536751"},{"fixed":"c7ebd8149ee519d27232e6e4940e9c02071b568b"},{"fixed":"36695d5eeeefe5a64b47d0336e7c8fc144e78182"},{"fixed":"61a348857e869432e6a920ad8ea9132e8d44c316"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"8cca5c85393a7a490d4d7942c24d73d29cc77b3e"},{"last_affected":"df2ca3271569367352835f981618e284fdc4ca94"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-26715.json"}}],"schema_version":"1.7.5"}
