CVE-2026-64464

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.
