kernel: net/iucv: filter frames in afiucv_hs_rcv() by ingress device

A flaw was found in the Linux kernel's AFIUCV Advanced Program-to-Program Communication over IUCV network protocol implementation. The afiucvhsrcv function, responsible for receiving frames, does not properly filter incoming frames based on the ingress network device. This oversight allows a loca...

CVE-2026-68397

A flaw was found in the Linux kernel's net/iucv module. The afiucvhsrcv function fails to properly manage socket references. This allows a local attacker to trigger a use-after-free vulnerability by concurrently closing a socket while it is being processed. Successful exploitation can lead to a...
