CVE-2026-93117 in Linux
要約
〜によって MITRE • 2026年09月18日
In the Linux kernel, the following vulnerability has been resolved:
usb: fix UAF when probe runs concurrent to dyn ID removal
Dynamic IDs are only guaranteed to be valid when usb_dynids_lock is held, as remove_id_store can free the node. Thus, make a copy in usb_probe_interface. Clarify the documentation that the id parameter is only valid during the probe.
USB serial has the same pattern, but it does not need fixing as the IDs cannot be removed via sysfs.
