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...

CVE-2026-53021

CVE-2026-53021 affects the Linux kernel SCSI target core (UNMAP bounds check). The root cause is an overflow where LBA + range can wrap on 64-bit overflow, with a fix that adds an overflow check mirroring the pattern used for WRITE_SAME. Publicly noted patches exist across multiple OS families: R...
