CVE-2024-50096: nouveau/dmem: Fix vulnerability in migrate_to_ram upon copy error

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.24% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 614bfb2050982d23d53d0d51c4079dba0437c883, 697e3ddcf1f8b68bd531fc34eead27c000bdf3e1, 73f75d2b5aee5a735cf64b8ab4543d5c20dbbdd9; cbl2 kernel 5.15.167.1-2 on CBL Mariner 2.0 5.15.173.1-1; cbl2 kernel 5.15.167.1-2 on CBL-Mariner 2.0 5.15.173.1-1.

Low priority for now. Upgrade to Linux Linux 614bfb2050982d23d53d0d51c4079dba0437c883, 697e3ddcf1f8b68bd531fc34eead27c000bdf3e1, 73f75d2b5aee5a735cf64b8ab4543d5c20dbbdd9; cbl2 kernel 5.15.167.1-2 on CBL Mariner 2.0 5.15.173.1-1; cbl2 kernel 5.15.167.1-2 on CBL-Mariner 2.0 5.15.173.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
