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...

CVE-2026-74575

A flaw was found in the Thunderbolt XDomain driver of the Linux kernel. A race condition can occur during the removal of a Thunderbolt cross-domain device XDomain. This allows a delayed work item to be queued after its cancellation but before the XDomain object is freed, leading to a use-after-fr...

CVE-2026-63893

A flaw was found in the Linux kernel's Thunderbolt property handling. A remote attacker, by acting as a malicious XDomain peer, could craft a special property entry that causes an integer overflow when calculating memory access. This overflow allows the system to read memory outside of the intend...

SUSE CVE-2026-63891

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: property: Cap recursion depth in tbpropertyparsedir A DIRECTORY entry's value field is used as the diroffset for a recursive call into tbpropertyparsedir with no depth counter. A crafted peer that chains DIRECTORY...

CVE-2026-63893

The connected documents describe a Linux kernel vulnerability in thunderbolt property parsing: a wrap of the 32-bit sum (entry->value + entry->length) allows an attacker-controlled offset to read memory beyond the property block. The root cause is not validating the sum with overflow checks...

CVE-2026-63891

The CVE affects the Linux kernel Thunderbolt property parser. A crafted peer can trigger a back‑reference loop in DIRECTORY entries, exhausting stack via __tb_property_parse_dir() because the value is used as dir_offset without a depth counter. The fix threads a depth counter through tb_property_...
