Summary
In the Linux kernel, the following vulnerability has been resolved: VMCI: fix race between vmci_host_setup_notify and vmci_ctx_unset_notify During our test, it is found that a warning can be trigger in try_grab_folio as follow: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 1678 at mm/gup.c:147 try_grab_folio+0x106/0x130 Modules linked in: CPU: 0 UID: 0 PID: 1678 Comm: syz.3.31 Not tainted 6.15.0-rc5 #163 PREEMPT(undef) RIP: 0010:try_grab_folio+0x106/0x130 Call Trace: <TASK> follow_huge_pmd+0x240/0x8e0 follow_pmd_mask.constprop.0.isra.0+0x40b/0x5c0 follow_pud_mask.constprop.0.isra.0+0x14a/0x170 follow_page_mask+0x1c2/0x1f0 __get_user_pages+0x176/0x950 __gup_longterm_locked+0x15b/0x1060 ? gup_fast+0x120/0x1f0 gup_fast_fallback+0x17e/0x230 get_user_pages_fast+0x5f/0x80 vmci_host_unlocked_ioctl+0x21c/0xf80 RIP: 0033:0x54d2cd ---[ end trace 0000000000000000 ]--- Digging into the source, context->notify_page may init by get_user_pages_fast and can be seen in vmci_ctx_unset_notify which will try to put_page.

              "value": "AV:L - The bug is reached only through `IOCTL_VMCI_SET_NOTIFY` on the `/dev/vmci` character device (`vmci_host_unlocked_ioctl` \u2192 `vmci_host_do_set_notify`), which requires local access to the host system. There is no remote or network-facing path into the VMCI host personality.\nAC:L - The attacker controls both sides of the race \u2014 two threads issuing `SET_NOTIFY` on the same fd, one with a non-zero `notify_uva` and one with zero \u2014 and `vmci_host_do_set_notify` is not serialized by `vmci_host_dev-\u003elock`, so the race can be looped indefinitely. Backing the UVA with a THP widens the window further, since `record_subpages()` in `gup_huge_pmd` publishes the page pointer into `context-\u003enotify_page` before the pin is validated.\nPR:L - There is no `capable()`, credential, or privilege check anywhere in `vmci_host_open()`, `vmci_ctx_create()`, or the SET_NOTIFY ioctl path \u2014 only the permissions on `/dev/vmci` gate access, and on VMware Workstation/Player hosts that node must be accessible to unprivileged users because the per-user VMX process opens it to create its VMCI context. A normal local user account is therefore sufficient.\nUI:N - Exploitation is entirely self-contained: the attacker opens `/dev/vmci`, issues `INIT_CONTEXT`, and races two `SET_NOTIFY` ioctls from its own threads. No victim action is required.\nS:U - The corruption occurs in host kernel memory and is exploited by a local host user, staying within the kernel\u0027s own security authority. Although VMCI is virtualization-related, this is the host-side personality driven by local ioctls, not a guest-to-host boundary crossing.\nC:H - `vmci_ctx_unset_notify()` calls `put_page()` on a pointer that `get_user_pages_fast()` published into `context-\u003enotify_page` before taking (or after rolling back) the reference, producing a refcount underflow that frees a page still mapped by userspace and still in use elsewhere. Once that page is recycled into kernel allocations while the attacker retains a user mapping, arbitrary kernel memory can be read.\nI:H - The same premature free gives the attacker a writable userspace mapping of a page the kernel later reallocates, a direct arbitrary-write primitive; additionally `context-\u003enotify` is left dangling into a released page and `ctx_signal_notify()` writes `true` through it at an attacker-chosen page offset when a datagram is queued. Both paths are readily leveraged for control-flow hijacking and privilege escalation.\nA:H - The race reliably trips `WARN_ON` in `try_grab_folio` (as reported by syzkaller) and, in the general case, causes page refcount underflow, double-free, and use-after-free of memory still in use, leading to kernel oops or panic. It can be triggered repeatedly by an unprivileged process."
