CVE-2026-64464 Detail

Description

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