Description OSIDB Bzimport 2026-10-18 15:31:49 UTC
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.
