Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An issue exists in the RDMA/hfi1 component where the
hfi1 free devdata() function unconditionally erases dd->unit, assuming the device was successfully inserted into the unit table. If the xa alloc irq() function fails, the unit remains zero-initialized. Consequently, the cleanup process may inadvertently remove an unrelated device located at index 0 of the unit table.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
