CVE-2026-89527

This Linux kernel vulnerability affects the svcrdma (RPC/NFS RDMA server) subsystem. The root cause is an improper error-path cleanup in svc_rdma_create(): when svc_rdma_create_listen_id() fails, the code calls kfree() on the transport structure, bypassing svc_xprt_free(). This leaks the net name...

CVE-2026-81003

CVE-2026-81003 affects the Linux kernel net/iucv subsystem (IBM s390 IUCV/HiperSockets). The function afiucv_hs_rcv() matched incoming frames to sockets using only four 8-byte name fields in the transport header, without verifying the ingress net_device . This allowed frames from any network devi...
