CVE-2022-49114 Information

Description

In the Linux kernel the following vulnerability has been resolved:

scsi: libfc: Fix use after free in fc_exch_abts_resp()

fc_exch_release(ep) will decrease the ep’s reference count. When the reference count reaches zero it is freed. But ep is still used in the following code which will lead to a use after free.

Return after the fc_exch_release() call to avoid use after free.
