CVE-2014-0038
Status: ModifiedMedium (6.9)—💥 Exploit
The compat_sys_recvmmsg function in net/compat.c in the Linux kernel before 3.13.2, when CONFIG_X86_X32 is enabled, allows local users to gain privileges via a recvmmsg system call with a crafted timeout pointer parameter.
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: 35%
- Percentile among all scored CVEs: 98
- Score date: 10/11/2026
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.
