{"id":"CVE-2024-50096","summary":"nouveau/dmem: Fix vulnerability in migrate_to_ram upon copy error","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnouveau/dmem: Fix vulnerability in migrate_to_ram upon copy error\n\nThe `nouveau_dmem_copy_one` function ensures that the copy push command is\nsent to the device firmware but does not track whether it was executed\nsuccessfully.\n\nIn the case of a copy error (e.g., firmware or hardware failure), the\ncopy push command will be sent via the firmware channel, and\n`nouveau_dmem_copy_one` will likely report success, leading to the\n`migrate_to_ram` function returning a dirty HIGH_USER page to the user.\n\nThis can result in a security vulnerability, as a HIGH_USER page that may\ncontain sensitive or corrupted data could be returned to the user.\n\nTo prevent this vulnerability, we allocate a zero page. Thus, in case of\nan error, a non-dirty (zero) page will be returned to the user.","modified":"2026-03-20T12:39:34.782639Z","published":"2024-11-05T17:04:58.689Z","related":["SUSE-SU-2024:4314-1","SUSE-SU-2024:4315-1","SUSE-SU-2024:4316-1","SUSE-SU-2024:4318-1","SUSE-SU-2024:4364-1","SUSE-SU-2024:4376-1","SUSE-SU-2024:4387-1","SUSE-SU-2025:20163-1","SUSE-SU-2025:20164-1","SUSE-SU-2025:20246-1","SUSE-SU-2025:20247-1","USN-7276-1","USN-7277-1","openSUSE-SU-2024:14500-1","openSUSE-SU-2025:14705-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/50xxx/CVE-2024-50096.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/614bfb2050982d23d53d0d51c4079dba0437c883"},{"type":"WEB","url":"https://git.kernel.org/stable/c/697e3ddcf1f8b68bd531fc34eead27c000bdf3e1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/73f75d2b5aee5a735cf64b8ab4543d5c20dbbdd9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/835745a377a4519decd1a36d6b926e369b3033e2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8c3de9282dde21ce3c1bf1bde3166a4510547aa9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ab4d113b6718b076046018292f821d5aa4b844f8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fd9bb7e996bab9b9049fffe3f3d3b50dee191d27"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/50xxx/CVE-2024-50096.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-50096"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5be73b690875f7eb2d2defb54ccd7f2f12074984"},{"fixed":"fd9bb7e996bab9b9049fffe3f3d3b50dee191d27"},{"fixed":"73f75d2b5aee5a735cf64b8ab4543d5c20dbbdd9"},{"fixed":"8c3de9282dde21ce3c1bf1bde3166a4510547aa9"},{"fixed":"614bfb2050982d23d53d0d51c4079dba0437c883"},{"fixed":"697e3ddcf1f8b68bd531fc34eead27c000bdf3e1"},{"fixed":"ab4d113b6718b076046018292f821d5aa4b844f8"},{"fixed":"835745a377a4519decd1a36d6b926e369b3033e2"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-50096.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
