CVE-2026-11743

The SF32LB MPI QSPI NOR flash driver drivers/flash/flashsf32lbmpiqspinor.c validated the flash offset and length on its read and write paths with the test offset + size data-size. Because offset is a signed offt while size is unsigned, a negative offset is converted to a large unsigned value and...
