CVE-2025-21957

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-21957
In the Linux kernel, the following vulnerability has been resolved: scsi: qla1280: Fix kernel oops when debug level > 2 A null dereference or oops exception will eventually occur when qla1280.c driver is compiled with DEBUG_QLA1280 enabled and ql_debug_level > 2. I think its clear from the code that the intention here is sg_dma_len(s) not length of sg_next(s) when printing the debug info.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: qla1280: Se corrige el error del kernel cuando el nivel de depuración > 2. Eventualmente, se producirá una desreferencia nula o una excepción de error cuando el controlador qla1280.c se compila con DEBUG_QLA1280 habilitado y ql_debug_level > 2. Creo que del código se desprende claramente que la intención aquí es sg_dma_len(s), no la longitud de sg_next(s) al imprimir la información de depuración.
