CVE-2026-68141 fixes a Linux kernel crash in the AF_IUCV networking code, but its practical exposure is far narrower than the word “networking” suggests: the affected path is for IBM s390 systems using AF_IUCV over HiperSockets, not ordinary x86 or Arm Linux hosts, Windows PCs, or typical WSL...

Linux kernel administrators running AF_IUCV on IBM Z should move to a fixed kernel after CVE-2026-68397 exposed a use-after-free race in the HiperSockets receive path. The flaw is confined to net/iucv/af_iucv.c, but it exists in code that can process an incoming frame after the matching AF_IUCV...
