On EX platforms, the Routing Engine (RE) might get crashed and result in VMcore, if the kernel sends a request to PFE for fetching the statistics of an Aggregated Ethernet (AE) with more than one member link. This issue appears when the member link gets lost for certain reasons in background and at the same time the kernel's request arrives. Since AE member link has lost, PFE might not send statistics response to kernel within 10 seconds(default time) and error might be returned. This invalid memory access might result in RE crash by generating VMcore. This could be a rare case scenario.

IS-IS adjacency might flap after committing configuration change on protocol MTU for IS-IS interface
Product-Group=junos
With IS-IS configured, committing configuration change on protocol MTU for IS-IS interface will trigger a sequence of events in Junos. The following specific sequence of events might cause IS-IS hello PDU to convey incorrect IP address in IS-IS TLV #132 (IP interface address field) which would result in the IS-IS adjacency flapping. This is a timing issue. == The following sequence of events trigger this issue when changing protocol MTU for IS-IS interface == 1. IP interface address is deleted. 2. IS-IS hello PDU is sent out. 3. MTU is changed to new value. 4. IP interface address is added back. When the IP interface address (IFA) is deleted due to protocol MTU (like inet MTU) being changed, if IS-IS hello PDU is sending out during this time, the current implementation will encode the router-id in IS-IS TLV #132 (IP interface address field). So, in this special case, the IS-IS hello PDU received by IS-IS neighbor will be marked as invalid because of address mismatch and the IS-IS adjacency will be down. In the fix of this PR, by default, Junos does not encode the router-id in IS-IS hello PDU when IFA is not present on interface. However, a hidden knob is given for the backward compatibility, and when this knob is configured, the router-id will be encoded in IS-IS hello PDU if IFA is not present on interface.

On QFX5K/EX4600/EX4650 platforms with IPv4 Filter-based forwarding (FBF) scenario, when IPv4 FBF is used with 802.1Q VLAN tag enabled layer-3 AE interfaces, the VLAN filtered configuration enabled by FBF filter will be stored in the VLAN filter processor (VFP) ternary content addressable memory (TCAM). But, in some cases of adding/deleting the configuration of the routing instances (then routing-instance) in FBF filter, the stale allocated entries in VFP TCAM might not be deleted from the system, the memory slices of VFP TCAM will be exhausted until it is run out. Finally, there are not enough memory slices left to store the VLAN filtered information for the forwarding routing instances, then the FBF filtered VLAN traffic will not be forwarded correctly since the FBF filters might not be programmed/processed on the system.
