HIGH

Linux Kernel 5.14-5.15.167, 5.16-6.1.112, 6.2-6.6.53, 6.7-6.10.12, 6.11-6.11.1 - Use-After-Free in efc_nport_vport_del

Title source: llm
STIX 2.1

Description

In the Linux kernel, the following vulnerability has been resolved: scsi: elx: libefc: Fix potential use after free in efc_nport_vport_del() The kref_put() function will call nport->release if the refcount drops to zero. The nport->release release function is _efc_nport_free() 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.
