Title
nvme: move stopping keep-alive into nvme_uninit_ctrl()
Summary
In the Linux kernel, the following vulnerability has been resolved: nvme: move stopping keep-alive into nvme_uninit_ctrl() Commit 4733b65d82bd ("nvme: start keep-alive after admin queue setup") moves starting keep-alive from nvme_start_ctrl() into nvme_init_ctrl_finish(), but don't move stopping keep-alive into nvme_uninit_ctrl(), so keep-alive work can be started and keep pending after failing to start controller, finally use-after-free is triggered if nvme host driver is unloaded. This patch fixes kernel panic when running nvme/004 in case that connection failure is triggered, by moving stopping keep-alive into nvme_uninit_ctrl(). This way is reasonable because keep-alive is now started in nvme_init_ctrl_finish().

NVMe/TCP has no mandatory authentication or encryption in typical deployments, so the attacker set extends to the network.\nAC:L - The remote target controls both sides of the interleaving \u2014 it chooses when to answer the keep-alive command and when to fail or stall the I/O-queue connect \u2014 and hosts retry connection setup automatically, giving unlimited attempts; the nvme-loop variant (loop.c:468-476, 573-618) has no race at all and leaks ka_work deterministically.\nPR:N - The attacker acts as the NVMe-oF target (or spoofs/MITMs the unauthenticated TCP connection) and needs no account, credentials, or privileges of any kind on the victim host. The vulnerable path runs during connection establishment, before any optional DH-HMAC-CHAP authentication is a factor.\nUI:N - Production NVMe-oF hosts connect automatically via nvmf-autoconnect at boot and via discovery-controller AEN-driven auto-connect (nvme-stas), so an attacker controlling the discovery/target endpoint can trigger repeated nvme_tcp_create_ctrl() attempts with no human action; the nvme-loop reset path (nvme_loop_reset_ctrl_work) is likewise entered automatically on controller error.\nS:U - The use-after-free occurs on kernel heap memory and is exploited within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed nvme_tcp_ctrl/nvme_loop_ctrl object can be reclaimed and re-sprayed by the attacker, and the stale timer/work dereference over that memory yields a controllable read and, once control flow is hijacked via work-\u003efunc, arbitrary kernel memory disclosure.\nI:H - The armed delayed_work lives inside the kfree()d controller, so timer expiry calls timer-\u003efunction and the worker calls work-\u003efunc from freed heap; reallocating that slab object gives the attacker a kernel function pointer under their control, i.e. arbitrary code execution and unrestricted modification of kernel state.\nA:H - Even without successful exploitation the stale delayed work fires on freed memory and reliably panics the kernel \u2014 this is exactly the reported crash from blktests nvme/004 \u2014 which is a complete denial of service on the storage host."

NVMe/TCP has no mandatory authentication or encryption in typical deployments, so the attacker set extends to the network.\nAC:L - The remote target controls both sides of the interleaving \u2014 it chooses when to answer the keep-alive command and when to fail or stall the I/O-queue connect \u2014 and hosts retry connection setup automatically, giving unlimited attempts; the nvme-loop variant (loop.c:468-476, 573-618) has no race at all and leaks ka_work deterministically.\nPR:N - The attacker acts as the NVMe-oF target (or spoofs/MITMs the unauthenticated TCP connection) and needs no account, credentials, or privileges of any kind on the victim host. The vulnerable path runs during connection establishment, before any optional DH-HMAC-CHAP authentication is a factor.\nUI:N - Production NVMe-oF hosts connect automatically via nvmf-autoconnect at boot and via discovery-controller AEN-driven auto-connect (nvme-stas), so an attacker controlling the discovery/target endpoint can trigger repeated nvme_tcp_create_ctrl() attempts with no human action; the nvme-loop reset path (nvme_loop_reset_ctrl_work) is likewise entered automatically on controller error.\nS:U - The use-after-free occurs on kernel heap memory and is exploited within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed nvme_tcp_ctrl/nvme_loop_ctrl object can be reclaimed and re-sprayed by the attacker, and the stale timer/work dereference over that memory yields a controllable read and, once control flow is hijacked via work-\u003efunc, arbitrary kernel memory disclosure.\nI:H - The armed delayed_work lives inside the kfree()d controller, so timer expiry calls timer-\u003efunction and the worker calls work-\u003efunc from freed heap; reallocating that slab object gives the attacker a kernel function pointer under their control, i.e. arbitrary code execution and unrestricted modification of kernel state.\nA:H - Even without successful exploitation the stale delayed work fires on freed memory and reliably panics the kernel \u2014 this is exactly the reported crash from blktests nvme/004 \u2014 which is a complete denial of service on the storage host."
