CVE-2026-98690 thunderbolt: Fix domain reference leak when DPRX read is canceled

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Fix domain reference leak when DPRX read is canceled tbtunnelonedp takes a domain reference which is only dropped once tbdptunnelactive has run on the work queue. If that work is cancelled that reference is leaked...

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-2026-98688

The Linux kernel contains a NULL pointer dereference vulnerability in the thunderbolt subsystem. A race condition exists between tb_remove_work() and tb_domain_remove() which can cause the tb->root_switch pointer to be dereferenced while it is NULL inside the tb_free_unplugged_xdomains() funct...

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...
