Type:
CWE-476
NULL Pointer Dereference
Publication date:

Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
KEYS: trusted: dcp: fix NULL dereference in AEAD crypto operation<br />
<br />
When sealing or unsealing a key blob we currently do not wait for<br />
the AEAD cipher operation to finish and simply return after submitting<br />
the request. If there is some load on the system we can exit before<br />
the cipher operation is done and the buffer we read from/write to<br />
is already removed from the stack. This will e.g. result in NULL<br />
pointer dereference errors in the DCP driver during blob creation.<br />
<br />
Fix this by waiting for the AEAD cipher operation to finish before<br />
resuming the seal and unseal calls.
