** Description changed:

- A flaw was found in the CXGB3 kernel driver when the network was
- considered congested.  The kernel would incorrectly misinterpret the
- congestion as an error condition and incorrectly free/clean up the skb.
- When the device would then send the skb's queued, these structures would
- be referenced and may panic the system or allow an attacker to escalate
- privileges in a use-after-free scenario.
+ drivers/infiniband/hw/cxgb3/iwch_cm.c in the Linux kernel before 4.5
+ does not properly identify error conditions, which allows remote
+ attackers to execute arbitrary code or cause a denial of service (use-
+ after-free) via crafted packets.
