staging: rtl8723bs: fix...
In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8723bs: fix mismatched free of HalData in rtw_sdio_if1_init()
padapter->HalData is allocated via vzalloc(), but incorrectly freed
using kfree() in the rtw_sdio_if1_init() error path. Using kfree() to
release this vmalloc-backed buffer can lead to memory corruption.
Use rtw_hal_data_deinit() to pair the free correctly and free
HalData with vfree().
The bug was first flagged by an experimental static analysis tool we
are developing for kernel memory-management bugs. Manual inspection
confirms that the issue is still present in current mainline.
An x86_64 allyesconfig build showed no new warnings. As we do not have
suitable RTL8723BS SDIO hardware to test with, no runtime testing was
able to be performed.
