CVE-2026-93103

In the Linux kernel, the following vulnerability has been resolved:

RDMA/hfi1: Preserve unit 0 on allocation failure

hfi1_free_devdata() assumes that the device was inserted into the unit
table and unconditionally erases dd->unit. If xa_alloc_irq() fails, the
zero-initialized unit remains zero, so full cleanup can remove an
unrelated device from index 0.

Release only the rdmavt allocation and return immediately while the unit
table has not acquired the device.
