Title
wifi: brcmfmac: slab-out-of-bounds read in brcmf_get_assoc_ies()
Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: slab-out-of-bounds read in brcmf_get_assoc_ies() Fix a slab-out-of-bounds read that occurs in kmemdup() called from brcmf_get_assoc_ies(). The bug could occur when assoc_info->req_len, data from a URB provided by a USB device, is bigger than the size of buffer which is defined as WL_EXTRA_BUF_MAX. Add the size check for req_len/resp_len of assoc_info. Found by a modified version of syzkaller.
