Details

In the Linux kernel, the following vulnerability has been resolved: dmaengine: ptdma: check for null desc before calling ptcmdcallback Resolves a panic that can occur on AMD systems, typically during host shutdown, after the PTDMA driver had been exercised. The issue was the ptissuepending() function is mistakenly assuming that there will be at least one descriptor in the Submitted queue when the function is called. However, it is possible that both the Submitted and Issued queues could be empty, which could result in ptcmdcallback() being mistakenly called with a NULL pointer. Ref: Bugzilla Bug 216856.
