medium Tenable Cloud Security Plugin ID 457179

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: usb: mtu3: unmap request DMA on queue
 failure mtu3_gadget_queue() maps the request before checking whether the QMU GPD ring can accept another
 transfer. the request is returned with -EAGAIN before it is linked on the endpoint request list if
 mtu3_prepare_transfer() fails. Normal completion and dequeue paths unmap requests from
 mtu3_req_complete(), but this error path never reaches that helper, so the DMA mapping is left active.
 Unmap the request before returning from the failed queue path. (CVE-2026-64337)

Solution

Update the linux library and its related packages to version 6.1.180-1 or later.
