  3. CVE-2022-49730
In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Resolve NULL ptr dereference after an ELS LOGO is aborted A use-after-free crash can occur after an ELS LOGO is aborted. Specifically, a nodelist structure is freed and then ndlp->vport->cfg_log_verbose is dereferenced in lpfc_nlp_get() when the discovery state machine is mistakenly called a second time with NLP_EVT_DEVICE_RM argument. Rework lpfc_cmpl_els_logo() to prevent the duplicate calls to release a nodelist structure.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: lpfc: Resolver la desreferencia de ptr NULL después de que se cancele un LOGOTIPO ELS Se puede producir un fallo de use-after-free después de que se cancele un LOGOTIPO ELS. Específicamente, se libera una estructura de lista de nodos y luego se desreferencia ndlp->vport->cfg_log_verbose en lpfc_nlp_get() cuando se llama por error a la máquina de estado de descubrimiento una segunda vez con el argumento NLP_EVT_DEVICE_RM. Reelabore lpfc_cmpl_els_logo() para evitar las llamadas duplicadas para liberar una estructura de lista de nodos.
