CVE-2023-3640
HIGH7.0
CVSS v3
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. 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.

Common questions
How do I fix CVE-2023-3640?
Published advisories record a fix for 156 affected products. The "How to fix" section on this page lists the fixed version and source advisory for each one, so apply the entry matching what you actually run.
Is CVE-2023-3640 being actively exploited?
Not that we know of. CVE-2023-3640 is not in the CISA Known Exploited Vulnerabilities catalog. Its EPSS score of 0.76% is the estimated probability that it will be exploited in the next 30 days. That is higher than 52% of all scored CVEs.
How severe is CVE-2023-3640?
CVE-2023-3640 has a CVSS v3 base score of 7.0, rated high. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.
What does CVE-2023-3640 affect?
Published advisories record a fix for bpftool (Red Hat / RHEL), bpftool (Rocky), bpftool-debuginfo (Red Hat / RHEL), bpftool-debuginfo (Rocky), and 152 more. Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.
