DEBIAN-CVE-2025-39742

In the Linux kernel, the following vulnerability has been resolved: RDMA: hfi1: fix possible divide-by-zero in findhwthreadmask The function divides number of online CPUs by numcoresiblings, and later checks the divider by zero. This implies a possibility to get and divide-by-zero runtime error...
