Description

In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: fix potential memory leak in rtw_init_drv_sw() In rtw_init_drv_sw(), there are various init functions are called to populate the padapter structure and some checks for their return value. However, except for the first one error path, the other five error paths do not properly release the previous allocated resources, which leads to various memory leaks. This patch fixes them and keeps the success and error separate. Note that these changes keep the form of `rtw_init_drv_sw()` in "drivers/staging/r8188eu/os_dep/os_intfs.c". As there is no proper device to test with, no runtime testing was performed.

Executive Summary

This vulnerability is a potential memory leak in the Linux kernel's rtl8723bs driver, specifically in the function rtw_init_drv_sw(). During initialization, multiple functions allocate resources to populate a structure, but if an error occurs after the first allocation, the previously allocated resources are not properly released. This leads to memory leaks. The patch fixes these leaks by ensuring that resources are correctly freed on error paths.

Impact Analysis

The vulnerability can cause memory leaks in the system when the rtl8723bs driver initializes. Over time, this can lead to increased memory usage, potentially degrading system performance or causing instability due to resource exhaustion.
