CVE-2026-80990

A flaw was found in the Linux kernel's Thunderbolt networking driver. An issue in the tbnetconnectedwork function can lead to a resource leak. When an unexpected HopID is allocated during an XDomain connection, the ID is not properly released, causing it to remain active without a reference. This...

CVE-2026-80990

CVE-2026-80990 is a resource-leak bug in the Linux kernel Thunderbolt networking (tbnet ) subsystem. In tbnet_connected_work(), the function requests a specific Rx HopID from tb_xdomain_alloc_in_hopid(), which uses ida_alloc_range() with the desired ID as a lower bound. If the requested ID is alr...
