EUVD-2026-103947

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Hold a router reference for each allocated HopID tbstop drops the reference to all DP tunnels but does not deactivate them, thus nothing cancels a dprxwork still in flight which holds its own tunnel reference and the...

CVE-2026-98693

The Linux kernel contains a vulnerability in the thunderbolt driver where tb_stop() drops references to DP tunnels without deactivating them. This allows tunnels to outlive tb_switch_remove(), causing dprx_work to hold references to freed IDAs, resulting in kernel warnings (e.g., ida_free called ...

EUVD-2026-103945

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Tear down inactive DP tunnels when the domain is stopped tbstop only tears down DMA tunnels so a DP tunnel that is still waiting for dprxwork to complete keeps that work queued while the routers are removed and the...

CVE-2026-98691

The Linux kernel contains a vulnerability where the thunderbolt subsystem fails to tear down inactive DP tunnels when a domain is stopped. Specifically, tb_stop() only handles DMA tunnels, allowing DP tunnels awaiting dprx_work to remain queued. This results in callbacks running against already t...

CVE-2026-98689

The Linux kernel contains a vulnerability in the thunderbolt component where tb_dp_dprx_work() checks the ->dprx_canceled flag before acquiring the tb->lock. This race condition allows the system to miss a tb_dp_dprx_stop() call, resulting in the kernel polling and running a callback for a ...

EUVD-2026-103943

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Don't access a DP tunnel after its DPRX read was canceled tbdpdprxwork checks -dprxcanceled before it takes tb-lock so it misses a tbdpdprxstop that could not cancel the already running work. It then polls the DPRX...
