CVE-2026-80584

CVE-2026-80584 is a heap buffer overflow in the Linux kernel's s390/qeth network driver, affecting the qeth_snmp_command() and qeth_l3_arp_query() ioctls. The root cause is an unsigned integer underflow: a user-supplied udata_len smaller than the fixed non-zero udata_offset causes the bounds-chec...
