CVE-2024-49891

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Validate hdwq pointers before dereferencing in reset/errata paths When the HBA is undergoing a reset or is handling an errata event, NULL ptr dereference crashes may occur in routines such as lpfc_sli_flush_io_rings(), lpfc_dev_loss_tmo_callbk(), or lpfc_abort_handler(). Add NULL ptr checks before dereferencing hdwq pointers that may have been freed due to operations colliding with a reset or errata event handler.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: lpfc: Validar punteros hdwq antes de desreferenciar en rutas de reinicio/errata Cuando el HBA está experimentando un reinicio o está manejando un evento de erratas, pueden ocurrir fallos de desreferencia de ptr NULL en rutinas como lpfc_sli_flush_io_rings(), lpfc_dev_loss_tmo_callbk() o lpfc_abort_handler(). Agregue verificaciones de ptr NULL antes de desreferenciar punteros hdwq que pueden haberse liberado debido a operaciones que colisionan con un controlador de eventos de reinicio o erratas.
