Unfortunately, the CoCo threat model means that the\nVM host cannot be trusted and may actively work against guests to\nextract secrets or manipulate computation. Since a malicious host can\nmodify or observe nearly all inputs to guests, the only remaining source\nof entropy for CoCo guests is RDRAND.\n\nIf RDRAND is broken -- due to CPU hardware fault -- the RNG as a whole\nis meant to gracefully continue on gathering entropy from other sources,\nbut since there aren\u0027t other sources on CoCo, this is catastrophic.\nThis is mostly a concern at boot time when initially seeding the RNG, as\nafter that the consequences of a broken RDRAND are much more\ntheoretical.\n\nSo, try at boot to seed the RNG using 256 bits of RDRAND output. If this\nfails, panic(). This will also trigger if the system is booted without\nRDRAND, as RDRAND is essential for a safe CoCo boot.\n\nAdd this deliberately to be \"just a CoCo x86 driver feature\" and not\npart of the RNG itself. Many device drivers and platforms have some\ndesire to contribute something to the RNG, and add_device_randomness()\nis specifically meant for this purpose.\n\nAny driver can call it with seed data of any quality, or even garbage\nquality, and it can only possibly make the quality of the RNG better or\nhave no effect, but can never make it worse.\n\nRather than trying to build something into the core of the RNG, consider\nthe particular CoCo issue just a CoCo issue, and therefore separate it\nall out into driver (well, arch/platform) code.\n\n  [ bp: Massage commit message. ]"

This is read/write access to the vulnerable component\u0027s platform, i.e. local.\nAC:L - The attacker directly creates the vulnerable condition \u2014 the host supplies guest CPUID and can simply not advertise X86_FEATURE_RDRAND, after which arch_get_random_longs() returns 0 and every remaining entropy input (cmdline, TSC, bootloader seed, interrupt/device timings) is host-supplied or host-observable. No unpredictable precondition is required; the same state also arises unaided when x86_init_rdrand() disables faulty RDRAND.\nPR:N - Privileges are measured against the vulnerable component \u2014 the CoCo guest kernel \u2014 and the host holds no account, credential, or privilege inside the guest at all. The weak seeding happens unconditionally during guest boot with no guest-side authentication.\nUI:N - The defective seeding occurs automatically in setup_arch() on every guest boot; no action by any guest user or administrator is needed.\nS:U - The vulnerable component (guest kernel RNG seeding) and the impacted component (that same guest\u0027s kernel and userspace secrets) sit in the same security authority. No guest-to-host escape or IOMMU boundary is crossed.\nC:H - With RDRAND absent the entire input pool consists of values the host chose or can observe, so the host can reconstruct the CRNG state and predict all get_random_bytes()/getrandom()/urandom output \u2014 disk-encryption keys, TLS/SSH private keys, session keys and IVs generated in the guest. That is a complete, total loss of the confidentiality guarantee CoCo exists to provide.\nI:H - Predictable nonces and keys let the attacker forge signatures, authentication tokens and MACs produced inside the guest, and predictable net_secret/ts_secret enable off-path TCP sequence and syncookie forgery for data injection. Predictable stack canaries (boot_init_stack_canary runs straight off the unseeded pool) and predictable randomization secrets additionally hand the attacker reliable control-flow-hijack primitives.\nA:H - Knowledge of the boot stack canary and other kernel randomization secrets converts otherwise-unreliable memory-corruption bugs into dependable code execution and full guest takeover, and predictable TCP ISN/syncookie secrets permit off-path RST injection that tears down the guest\u0027s connections."

Commit\nfb6791d100d1b started exploiting this behavior to speed up filesystem\nunmount: gfs2 would simply free glocks it didn\u0027t want to unlock and then\nrelease the lockspace.  This didn\u0027t take the bast callbacks for\nasynchronous lock contention notifications into account, which remain\nactive until until a lock is unlocked or its lockspace is released.\n\nTo prevent those callbacks from accessing deallocated objects, put the\nglocks that should not be unlocked on the sd_dead_glocks list, release\nthe lockspace, and only then free those glocks.\n\nAs an additional measure, ignore unexpected ast and bast callbacks if\nthe receiving glock is dead."

The DLM interconnect is routable IP, not restricted to a single L2 segment.\nAC:L - The attacker fully controls the contention side and can hold conflicting locks on many resources continuously so that a bast is guaranteed to land in the unmount window, which is wide (it spans `truncate_inode_pages_final()` and `gfs2_delete_debugfs_file()`); unmounts of clustered GFS2 volumes are routine and repeatable events in pacemaker-managed clusters, so the race is reliably winnable.\nPR:N - No credentials or privileges on the victim node are needed \u2014 the DLM peer\u0027s lock request is not authenticated per-user by the target, and an ordinary unprivileged user on any cluster node generates the required contention with plain file access on the shared filesystem.\nUI:N - No victim action is solicited by the attacker; the unmount is a routine cluster/administrative operation and the callback fires automatically from the DLM workqueue.\nS:U - The freed object and the corrupted state are both kernel memory in the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - A use-after-free on a `gfs2_glock` slab object allows the freed allocation to be reclaimed by attacker-influenced data and then read/leaked through glock state and the subsequent `dump_glock_func` path, giving arbitrary kernel-memory disclosure potential.\nI:H - `gfs2_glock_cb()` writes into the freed object (lockref count, `gl_flags`, `gl_demote_state`) and then queues `\u0026gl-\u003egl_work`, so a reallocated object supplies the `delayed_work` timer/work function pointer \u2014 a control-flow hijack and arbitrary-write primitive.\nA:H - Even unexploited, the UAF corrupts a spinlock and refcount in freed memory and reaches `BUG_ON`/`BUG()` in `gdlm_ast()`, causing kernel oops or panic on the unmounting node."

Attack requires local access to the system or container hosting the ionic netdev.\nAC:L - The upstream reproducer is a deterministic three-command sequence (`ethtool -L ... rx 1 tx 1 combined 0`, then `combined 1`, then `combined 4`) with no race and no dependence on memory layout or system state the attacker cannot influence. The link-status event that drives the crashing deferred work is generated by the reconfiguration itself via `ionic_link_status_check_request()`.\nPR:L - Both entry points gate on namespace-relative CAP_NET_ADMIN (`ns_capable(net-\u003euser_ns, CAP_NET_ADMIN)` in net/ethtool/ioctl.c:2912 and `GENL_UNS_ADMIN_PERM` in net/ethtool/netlink.c:921), which an unprivileged user holds inside their own user namespace. ionic exposes SR-IOV VFs that are routinely delegated into container network namespaces by SR-IOV CNI, so a basic container user reaches `ionic_set_channels` without any host-root privilege.\nUI:N - The entire sequence is attacker-driven from a single process; no administrator or victim action is needed. The queue restart that reaches `ionic_qcq_enable()` is triggered automatically by the attacker\u0027s own reconfiguration.\nS:U - The corruption and the crash are confined to the kernel\u0027s own security authority \u2014 there is no hypervisor, IOMMU, or DMA boundary being crossed. This is standard in-kernel memory corruption, so the vulnerable component and impacted component share one authority.\nC:H - Re-enabling a NAPI that `netif_napi_del()` already unlinked leaves it schedulable from the still-registered IRQ while the containing `struct ionic_qcq` is `devm_kfree()`d, so `net_rx_action()` polls freed slab memory \u2014 a use-after-free that yields an arbitrary kernel-memory read primitive once the object is resprayed.\nI:H - The same use-after-free makes `n-\u003epoll` an indirect call through freed, attacker-sprayable slab memory, giving a control-flow-hijack and arbitrary-write primitive. Per UAF scoring guidance this is High integrity impact, not a mere crash.\nA:H - `napi_enable()` hits `BUG_ON(!test_bit(NAPI_STATE_SCHED, \u0026val))` (net/core/dev.c:6665) and kills the kworker while it holds `lif-\u003equeue_lock`, which is then leaked permanently \u2014 every subsequent `ionic_open`/`ionic_stop`/ethtool path blocks on it while holding `rtnl_lock`, deadlocking the whole networking control plane until reboot (immediate panic with `panic_on_oops=1`)."
