Vulnerability in Linux kernel (CVE-2025-38582)
Summary
Vulnerability in Linux kernel (CVE-2025-38582). Successful exploitation can lead to full system takeover.
Original description
The description as published by the source.
In the Linux kernel, the following vulnerability has been resolved:
RDMA/hns: Fix double destruction of rsv_qp
rsv_qp may be double destroyed in error flow, first in free_mr_init(),
and then in hns_roce_exit(). Fix it by moving the free_mr_init() call
into hns_roce_v2_init().
list_del corruption, ffff589732eb9b50->next is LIST_POISON1 (dead000000000100)
