Based on the previous CVE-2023-0597, the 'Randomize per-cpu entry area' feature was implemented in /arch/x86/mm/cpu_entry_area.c, which works through the init_cea_offsets() function when KASLR is enabled. However, despite this feature, there is still a risk of per-cpu entry area leaks. This issue could allow a local user to gain access to some important data with memory in an expected location and potentially escalate their privileges on the system.\n\ud83d\udccf Published: 2023-07-24T15:19:29.983Z\n\ud83d\udccf Modified: 2025-04-15T11:40:03.124Z\n\ud83d\udd17 References:\n1. https://access.redhat.com/errata/RHSA-2023:6583\n2. https://access.redhat.com/security/cve/CVE-2023-3640\n3. https://bugzilla.redhat.com/show_bug.cgi?id=2217523", "creation_timestamp": "2025-04-15T11:55:55.000000Z"} {"uuid": "ca1e67c0-6d42-4214-a1be-ac0ff28a6bc2", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "2a075640-a300-48a4-bb44-bc6130783b9b", "vulnerability": "RHSA-2023:6583", "type": "seen", "source": "https://t.me/DarkWebInformer_CVEAlerts/11782", "content": "\ud83d\udd17 DarkWebInformer.com - Cyber Threat Intelligence\n\ud83d\udccc CVE ID: CVE-2023-3640\n\ud83d\udd25 CVSS Score: 7 (cvssV3_1, Vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H)\n\ud83d\udd39 Description: A possible unauthorized memory access flaw was found in the Linux kernel's cpu_entry_area mapping of X86 CPU data to memory, where a user may guess the location of exception stacks or other important data.
