CVE-2026-98692

The Linux kernel contains a memory leak vulnerability in the thunderbolt subsystem. Specifically, the tb_tunnel_alloc_dp() function accepts an optional callback; if this callback is missing, tb_dp_dprx_start() reads capabilities synchronously and fails to queue work. This causes the tunnel refere...

CVE-2026-98691 thunderbolt: Tear down inactive DP tunnels when the domain is stopped

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-2026-98690

The Linux kernel contains a vulnerability in the thunderbolt driver where a domain reference is leaked when a DPRX read is canceled. Specifically, the tb_tunnel_one_dp() function takes a reference that is only dropped once; if tb_dp_tunnel_active() work is canceled, the reference remains leaked. ...

CVE-2026-98689 thunderbolt: Don't access a DP tunnel after its DPRX read was canceled

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...

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 ...

CVE-2026-98687

The Linux kernel thunderbolt driver contains a heap out-of-bounds read vulnerability in the tb_xdp_properties_request() function. A malicious peer can set an XDomain length field to 63, leading the driver to treat the data as 48 dwords despite only allocating room for 45. This mismatch causes mem...
