CVE-2026-80710

CVE-2026-80710 affects the s390/dasd subsystem of the Linux kernel. In dasd_eckd_check_device_format(), the variable fmt_buffer_size is declared as a 32-bit int, but the expression trkcount * rpt_max * sizeof(struct eckd_count) is evaluated at 64-bit width. When the track range (controlled by cal...
