Description
In the Linux kernel, the following vulnerability has been resolved:
nfc: st21nfca: validate ISO15693 inventory length
The ISO15693 inventory helper removes a two-byte prefix without checking
that it exists, then accepts a one-byte remainder before reading data[1] as
the DSFID.
Require the prefix and at least two remaining bytes before copying the UID
data and reading the DSFID.
