Summary
In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8723bs: os_dep: avoid NULL pointer dereference in rtw_cbuf_alloc
The return value of kzalloc_flex() is used without 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.
