CVE-2026-68141

The CVE-2026-68141 issue affects the Linux kernel’s af_iucv path. afiucv_hs_callback_syn() may allocate a child socket; if allocation fails, nsk becomes NULL and the code may call iucv_sock_kill(nsk), which dereferences a NULL pointer. The result is a NULL pointer dereference causing a system cra...
