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.
Affected configurations
• linux linux kernel (>= 4.12 < 5.15.75)
• linux linux kernel (>= 5.16 < 5.19.17)
• linux linux kernel (>= 6.0 < 6.0.3)
