CVE-2026-53021

A flaw was found in the Linux kernel's SCSI target core. The sbcexecuteunmap function, which handles UNMAP operations, is vulnerable to an integer overflow. This vulnerability occurs because the bounds check for the Logical Block Address LBA and range does not prevent a 64-bit overflow. An attack...
