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"}
