Description OSIDB Bzimport 2025-01-15 14:01:46 UTC 
In the Linux kernel, the following vulnerability has been resolved:

RDMA/siw: Remove direct link to net_device

Do not manage a per device direct link to net_device. Rely
on associated ib_devices net_device management, not doubling
the effort locally. A badly managed local link to net_device
was causing a 'KASAN: slab-use-after-free' exception during
siw_query_port() call.
