Description
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: fixed hclge_fetch_pf_reg accesses bar space out of bounds issue
The TQP BAR space is divided into two segments. TQPs 0-1023 and TQPs
1024-1279 are in different BAR space addresses. However,
hclge_fetch_pf_reg does not distinguish the tqp space information when
reading the tqp space information. When the number of TQPs is greater
than 1024, access bar space overwriting occurs.
The problem of different segments has been considered during the
initialization of tqp.io_base. Therefore, tqp.io_base is directly used
when the queue is read in hclge_fetch_pf_reg.
The error message:
Unable to handle kernel paging request at virtual address ffff800037200000
pc : hclge_fetch_pf_reg+0x138/0x250 [hclge]
