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.

Affected configurations

• linux linux kernel (>= 5.14 < 5.15.168) • linux linux kernel (>= 5.16 < 6.1.113) • linux linux kernel (>= 6.2 < 6.6.54) • linux linux kernel (>= 6.7 < 6.10.13) • linux linux kernel (>= 6.11 < 6.11.2)
