The CVE record's CNA (kernel.org) lists Linux versions 5.10.241 up to but not including 5.10.273, 5.15.190 up to but not including 5.15.224, 6.1.147 up to but not including 6.1.191 and 6.6.100 up to but not including 6.6.160 as affected, and Linux versions before 6.16 and 7.3 and later as unaffected. No release containing a fix is confirmed on record.

In the Linux kernel, the following vulnerability has been resolved:

usb: hub: use shorter 120ms post resume hold for SS root hubs

Holding a USB3 hub PM runtime reference for 200ms at hub resume triggers an AMD platform issue. Users running Android adb report crashes after adb has been polling and waking up the USB subsystem once a second for some time. Vendors are working on a solution. Disabling USB runtime PM is one way to prevent this issue, but it is also proven that reducing the hold time to 120ms in resume also mitigates it. See Link for more details.

Reducing the hold time to 120ms for the USB3 roothub is in itself a valid change and optimization, as the current 200ms is excessive: a root hub has no upstream suspended hub whose wake propagation needs to be accounted for, but still need some time for USB3 link training to complete.

Keep the 200ms hold for external hubs that commit 8f5b7e2bec1c ("usb: hub: fix detection of high tier USB3 devices behind suspended hubs") is intended for.

No released fix is confirmed on this page, but CISA's timeline does not wait for a fix's release: it starts when an agency identifies the flaw on an asset and updates the CDM Agency and Federal Dashboard, and the directive counts patching, decommissioning the system or another action as remediation. Until a fixed release is applied, mitigate as this page's verdict says. In the directive's words, “Fix on system upgrade” means that, “unless conditions change”, the vulnerability “should be remediated the next time the vulnerable asset receives a scheduled major upgrade or rebuild”: its timelines are “dynamic as facts change”, and a KEV listing shortens them.

The score's inputs: In CISA KEV no (CISA's KEV catalog) · Automatable no (CISA's BOD 26-04 default) · Technical impact total (CISA's BOD 26-04 default). Where an input reads “CISA's BOD 26-04 default”, no one has published it for this CVE, and CISA's implementation guidance says: “If “Automatable” and “Technical Impact” information items about a CVE ID are not available and the CVE ID is not in the KEV Catalog, CISA will treat its values as “no” and “total,” respectively, until CISA or a third party provides metadata about the CVE ID. CISA will always provide the Vulnrichment data for a CVE ID listed in the KEV Catalog.” Whether your system is publicly exposed is yours to answer.
