CVE-2026-93103

Estado: RecibidaSin puntuar—

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.
