{"id":"CVE-2024-50112","summary":"x86/lam: Disable ADDRESS_MASKING in most cases","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nx86/lam: Disable ADDRESS_MASKING in most cases\n\nLinear Address Masking (LAM) has a weakness related to transient\nexecution as described in the SLAM paper[1]. Unless Linear Address\nSpace Separation (LASS) is enabled this weakness may be exploitable.\n\nUntil kernel adds support for LASS[2], only allow LAM for COMPILE_TEST,\nor when speculation mitigations have been disabled at compile time,\notherwise keep LAM disabled.\n\nThere are no processors in market that support LAM yet, so currently\nnobody is affected by this issue.\n\n[1] SLAM: https://download.vusec.net/papers/slam_sp24.pdf\n[2] LASS: https://lore.kernel.org/lkml/20230609183632.48706-1-alexander.shishkin@linux.intel.com/\n\n[ dhansen: update SPECULATION_MITIGATIONS -\u003e CPU_MITIGATIONS ]","modified":"2026-04-16T04:39:24.980237580Z","published":"2024-11-05T17:10:44.623Z","related":["USN-7276-1","USN-7277-1","openSUSE-SU-2024:14500-1","openSUSE-SU-2025:14705-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/50xxx/CVE-2024-50112.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3267cb6d3a174ff83d6287dcd5b0047bbd912452"},{"type":"WEB","url":"https://git.kernel.org/stable/c/60a5ba560f296ad8da153f6ad3f70030bfa3958f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/690599066488d16db96ac0d6340f9372fc56f337"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/50xxx/CVE-2024-50112.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-50112"},{"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":"6449dcb0cac738219d13c618af7fd8664735f99d"},{"fixed":"60a5ba560f296ad8da153f6ad3f70030bfa3958f"},{"fixed":"690599066488d16db96ac0d6340f9372fc56f337"},{"fixed":"3267cb6d3a174ff83d6287dcd5b0047bbd912452"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-50112.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:H/A:H"}]}
