- Summary
- CVE-2024-50096 affecting package kernel for versions less than 5.15.173.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
nouveau/dmem: Fix vulnerability in migratetoram upon copy error
The
nouveau_dmem_copy_onefunction 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_onewill likely report success, leading to themigrate_to_ramfunction 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.
