Aug 4 RESCORED — CVE-2024-50096 (Linux). CVSS 7.3 → 5.5 (NVD).
Description
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.
