CVE-2023-53415 (CNNVD-202509-2938)
中文标题:
Linux kernel 安全漏洞
英文标题:
USB: dwc3: fix memory leak with using debugfs_lookup()
漏洞描述
中文描述:
Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞,该漏洞源于未正确处理debugfs_lookup返回值,可能导致内存泄漏。
英文描述:
In the Linux kernel, the following vulnerability has been resolved: USB: dwc3: fix memory leak with using debugfs_lookup() When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once. Note, the root dentry for the debugfs directory for the device needs to be saved so we don't have to keep looking it up, which required a bit more refactoring to properly create and remove it when needed.
