| Sažetak |
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. |
