**Name of the Vulnerable Software and Affected Versions** Linux kernel version 5.10.142-1 Linux kernel version 5.15.0-33 Linux kernel version 5.15.0-70 **Description** An error handling issue exists in the `wfx init common()` function within the staging wfx driver. A specific error handler returns without calling the `ieee80211 free hw(hw)` function, which can lead to a memory leak. **Recommendations** Update Linux kernel version 5.10.142-1 to a patched version. Update Linux kernel version 5.15.0-33 to a patched version. Update Linux kernel version 5.15.0-70 to a patched version.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A potential memory leak was found in the Linux kernel, specifically in the r871xu drv init() function. This issue occurs when r8712 init drv sw() fails, causing memory allocated by r8712 alloc io queue() in r8712 usb dvobj init() to not be properly released. The memory leak is due to the lack of a call to r8712 free io queue() in r8712 usb dvobj deinit(). To fix this, r8712 free io queue() should be called in r8712 usb dvobj deinit(). Additionally, the code has been modified to move r8712 usb dvobj deinit() into r871xu dev remove() and remove r8712 free io queue() from r8712 free drv sw() for better code understanding. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A potential memory leak has been identified in the Linux kernel, specifically in the tracing/histogram component. The issue arises due to a missing kfree() call on an error path, which fails to free the memory allocated by kstrdup(). This can be resolved by freeing the memory via kfree(p), where p = param = kstrdup(data->params[i], GFP KERNEL). **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
