CVE-2014-3940
Status: ModifiedMedium (4)—
The Linux kernel through 3.14.5 does not properly consider the presence of hugetlb entries, which allows local users to cause a denial of service (memory corruption or system crash) by accessing certain memory locations, as demonstrated by triggering a race condition via numa_maps read operations during hugepage migration, related to fs/proc/task_mmu.c and mm/mempolicy.c.
CVSS
- Version: 2.0
- Vector: AV:L/AC:H/Au:N/C:N/I:N/A:C
- Base score: 4
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.27%
- Percentile among all scored CVEs: 18
- 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).
