CVE-2025-7039
Status: DeferredLow (3.7)—
A flaw was found in glib. An integer overflow during temporary file creation leads to an out-of-bounds memory access, allowing an attacker to potentially perform path traversal or access private temporary file content by creating symbolic links. This vulnerability allows a local attacker to manipulate file paths and access unauthorized data. The core issue stems from insufficient validation of file path lengths during temporary file operations.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N
- Base score: 3.7
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.40%
- Percentile among all scored CVEs: 31
- Score date: 10/1/2026
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).
