CVE-2024-49852: scsi: elx: libefc: Fix potential use after free in efc_nport_vport_del()

Published Oct 21, 2024
·
Updated

In the Linux kernel, the following vulnerability has been resolved:

scsi: elx: libefc: Fix potential use after free in efcnportvportdel()

The krefput() function will call nport->release if the refcount drops to zero. The nport->release release function is efcnportfree() which frees "nport". But then we dereference "nport" on the next line which is a use after free. Re-order these lines to avoid the use after free.
