CVE-2026-80989

A flaw was found in the Linux kernel's Thunderbolt networking subsystem. When a Thunderbolt connection fails to establish, the system may not correctly update its state, leading to repeated attempts to tear down an already inactive connection. This can result in a kernel warning and, under certai...

CVE-2026-89737

A flaw was found in the Linux kernel's USB Type-C Thunderbolt driver. The tbtaltmoderemove function fails to properly disable and drain work items before freeing associated plug and cable references. This oversight can lead to a use-after-free vulnerability, where the system attempts to access...

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...
