Title
nouveau/dmem: Fix vulnerability in migrate_to_ram upon copy error
Summary
In the Linux kernel, the following vulnerability has been resolved: nouveau/dmem: Fix vulnerability in migrate_to_ram upon copy error The `nouveau_dmem_copy_one` function ensures that the copy push command is sent to the device firmware but does not track whether it was executed successfully. In the case of a copy error (e.g., firmware or hardware failure), the copy push command will be sent via the firmware channel, and `nouveau_dmem_copy_one` will likely report success, leading to the `migrate_to_ram` function returning a dirty HIGH_USER page to the user. This can result in a security vulnerability, as a HIGH_USER page that may contain sensitive or corrupted data could be returned to the user. To prevent this vulnerability, we allocate a zero page. Thus, in case of an error, a non-dirty (zero) page will be returned to the user.

There is no network-facing path to nouveau_dmem_migrate_to_ram().\nAC:L - The attacker fully controls both the migration (SVM_BIND MIGRATE) and the CPU fault that triggers migrate_to_ram, and can repeat it arbitrarily; the copy-error precondition was not a rare fault but the routine state of the driver, since the copy engine channel was non-privileged and every push hit HCE_PRIV errors (fixed separately in 04e0481526e3). Within a vulnerable configuration the leak is deterministic and reproducible on demand.\nPR:L - Both SVM ioctls are marked DRM_RENDER_ALLOW, requiring neither DRM_AUTH/DRM_MASTER nor any capability \u2014 only ordinary render-node access, which desktop session users hold by default and which is commonly exposed inside GPU-enabled containers. No root or CAP_SYS_ADMIN is needed.\nUI:N - The attacker performs every step in its own process \u2014 init SVM, migrate its own pages to VRAM, then touch them \u2014 with no action by any other user. No victim participation is required.\nS:U - The leaked page is installed into the attacking process\u0027s own address space by the kernel that owns the vulnerable code; no VM, IOMMU, or sandbox authority boundary is crossed. Impact stays within the kernel/userspace security authority.\nC:H - The user is handed a full page of uninitialized buddy-allocator memory whose contents are whatever was last freed system-wide \u2014 page cache (arbitrary file data), other processes\u0027 freed anonymous memory, freed kernel pages containing keys, credentials, and pointers usable to defeat KASLR. The attacker can loop the migrate/fault cycle over a large VA range to harvest recycled physical pages continuously, amounting to a broad arbitrary-memory-read primitive rather than a bounded leak.\nI:H - A full page of a process\u0027s SVM-backed data is silently replaced with allocator-recycled content while the fault reports success (ret == 0, no SIGBUS), so the corruption is undetectable to the application. An attacker who grooms the page allocator can influence which freed content is recycled, injecting chosen bytes into the address space of a victim \u2014 potentially privileged \u2014 process using nouveau SVM.\nA:L - The kernel itself does not panic, but the application silently consumes garbage in place of its real data, which can crash or wedge the consuming process. The impact is degradation of the affected workload rather than a system-wide denial of service."
