Description OSIDB Bzimport 2024-12-27 14:01:16 UTC 
In the Linux kernel, the following vulnerability has been resolved:

RDMA/hns: Fix NULL pointer derefernce in hns_roce_map_mr_sg()

ib_map_mr_sg() allows ULPs to specify NULL as the sg_offset argument.
The driver needs to check whether it is a NULL pointer before
dereferencing it.
