What it is

In the Linux kernel, the following vulnerability has been resolved:

staging: rtl8723bs: os_dep: avoid NULL pointer dereference in rtw_cbuf_alloc

ensuring that the allocation succeeded, and the

pointer is dereferenced unconditionally.

Guard the access to the allocated structure to

avoid a potential NULL pointer dereference if the

allocation fails.
