The SCardReleaseContext function normally releases resources associated
with the given handle (including “cardsList”) and clients should
cease using this handle. However, a malicious client can make the daemon
invoke SCardReleaseContext and continue issuing other commands that use
“cardsList”, resulting in a use-after-free. When SCardReleaseContext

A local attacker could use a malicious client to connect to pcscd’s
Unix socket, possibly resulting in a Denial of Service condition or
privilege escalation since the daemon is running as root.
There is no known workaround at this time.
