In the Linux kernel, the following vulnerability has been resolved:
nfc: pn533: Clear nfc_target before being used
Fix a slab-out-of-bounds read that occurs in nla_put() called from nfc_genl_send_target() when target->sensb_res_len, which is duplicated from an nfc_target in pn533, is too large as the nfc_target is not properly initialized and retains garbage values. Clear nfc_targets with memset() before they are used.
Found by a modified version of syzkaller.
