Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
xhci: sideband: fix ring sg table pages leak<br />
<br />
xhci_ring_to_sgtable() allocates a temporary pages array and<br />
uses it to build the returned sg_table with<br />
sg_alloc_table_from_pages().<br />
<br />
The error paths free the pages array, but the success path<br />
returns the sg_table without freeing it. This leaks the temporary<br />
array every time a sideband client gets an endpoint or event ring<br />
buffer.<br />
<br />
Free the pages array after sg_alloc_table_from_pages() succeeds.<br />
The returned sg_table has its own scatterlist entries and does not<br />
depend on the temporary array after construction.
