Title
RDMA/cxgb4: Added NULL check for lookup_atid
Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/cxgb4: Added NULL check for lookup_atid The lookup_atid() function can return NULL if the ATID is invalid or does not exist in the identifier table, which could lead to dereferencing a null pointer without a check in the `act_establish()` and `act_open_rpl()` functions. Add a NULL check to prevent null pointer dereferencing. Found by Linux Verification Center (linuxtesting.org) with SVACE.

Atid-table exhaustion, which makes the freed slot read back as NULL, is likewise inducible by flooding concurrent connects.\nPR:N - `act_establish()` and `act_open_rpl()` run at TCP handshake completion/failure, long before MPA negotiation or any credential exchange, so the peer driving the condition is entirely unauthenticated. No privileges on the target are needed for the remote side of the attack.\nUI:N - No victim action is required \u2014 the connection attempts are made by already-running RDMA ULPs or reconnect loops, and the CPL processing happens asynchronously in the `iw_cxgb4` workqueue.\nS:U - The NULL dereference crashes the kernel that contains the flaw; no security authority boundary such as a VM or IOMMU domain is crossed.\nC:N - The dereference is of a NULL `struct c4iw_ep *` at small member offsets (`com.mutex`, `dst`, `com.local_addr`), all below `mmap_min_addr`, so it faults immediately with no attacker-mapped page and yields no read primitive or information disclosure.\nI:N - No memory is written through the NULL pointer before the fault, and the bug provides no write primitive or control-flow hijack \u2014 it is a pure crash.\nA:H - The dereference produces a kernel oops in workqueue context, which is a full panic on `panic_on_oops` systems; even absent that, the ordered `iw_cxgb4` workqueue is wedged, stalling all RDMA connection management for the adapter."

No privileges on the target are needed for the remote side of the attack.\\nUI:N - No victim action is required \\u2014 the connection attempts are made by already-running RDMA ULPs or reconnect loops, and the CPL processing happens asynchronously in the `iw_cxgb4` workqueue.\\nS:U - The NULL dereference crashes the kernel that contains the flaw; no security authority boundary such as a VM or IOMMU domain is crossed.\\nC:N - The dereference is of a NULL `struct c4iw_ep *` at small member offsets (`com.mutex`, `dst`, `com.local_addr`), all below `mmap_min_addr`, so it faults immediately with no attacker-mapped page and yields no read primitive or information disclosure.\\nI:N - No memory is written through the NULL pointer before the fault, and the bug provides no write primitive or control-flow hijack \\u2014 it is a pure crash.\\nA:H - The dereference produces a kernel oops in workqueue context, which is a full panic on `panic_on_oops` systems; even absent that, the ordered
