Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
