CVE-2026-80990

In the Linux kernel, the following vulnerability has been resolved: net: thunderbolt: Release the Rx HopID that was handed out on mismatch tbxdomainallocinhopid passes the wanted HopID to idaallocrange as the lower bound, so a taken id is not an error there: the allocator returns the next free on...

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...

CVE-2026-74691

CVE-2026-74691 is a teardown ordering bug in the Linux kernel Thunderbolt network driver (net: thunderbolt / tbnet). The driver stops its DMA rings and frees frame buffers before deactivating the high-speed DMA paths, but the setup path was previously fixed to enable paths last. Teardown was neve...
