CVE-2026-98634

The Linux kernel contains a vulnerability in the scsi: sd_zbc component where sd_zbc_read_zones() uses 64-bit arithmetic to compute zone counts but stores them in an unsigned int field. This results in silent truncation for counts exceeding 32 bits, causing the system to use incorrect values for ...
