Title
dmaengine: idxd: Fix potential null dereference on pointer status
Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: Fix potential null dereference on pointer status
There are calls to idxd_cmd_exec that pass a null status pointer however
a recent commit has added an assignment to *status that can end up
with a null pointer dereference. The function expects a null status
pointer sometimes as there is a later assignment to *status where
status is first null checked. Fix the issue by null checking status
before making the assignment.
Addresses-Coverity: ("Explicit null dereferenced")
Severity ?
No CVSS data available.
