CVE-2010-4347
Status: ModifiedMedium (6.9)—💥 Exploit
The ACPI subsystem in the Linux kernel before 2.6.36.2 uses 0222 permissions for the debugfs custom_method file, which allows local users to gain privileges by placing a custom ACPI method in the ACPI interpreter tables, related to the acpi_debugfs_init function in drivers/acpi/debugfs.c.
CVSS
- Version: 2.0
- Vector: AV:L/AC:M/Au:N/C:C/I:C/A:C
- Base score: 6.9
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 2.20%
- Percentile among all scored CVEs: 82
- Score date: 10/7/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
💥 Public exploits
Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
