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

nfc: fix potential NULL pointer deref in nfc_genl_dump_ses_done

The done() netlink callback nfc_genl_dump_ses_done() should check if
received argument is non-NULL, because its allocation could fail earlier
in dumpit() (nfc_genl_dump_ses()).
