Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
nvme-pci: fix dma mapping leak on data setup error<br />
<br />
We&#39;re leaking the initial DMA mapping during iteration if we fail to<br />
allocate the tracking descriptor for both PRP and SGL. Unmap the<br />
iterator directly; we can&#39;t use the existing unmap helper because it<br />
depends on the tracking descriptor being successfully allocated, so a<br />
new one for an in-use iterator is provided.<br />
<br />
The mappings were also leaking when the driver detects an invalid<br />
bio_vec when mapping PRPs, so fix that too.
