CVE-2011-3259
Status: ModifiedMedium (5)—
The kernel in Apple iOS before 5 and Apple TV before 4.4 does not properly recover memory allocated for incomplete TCP connections, which allows remote attackers to cause a denial of service (resource consumption) by making many connection attempts.
CVSS
- Version: 2.0
- Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
- Base score: 5
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 2.44%
- Percentile among all scored CVEs: 84
- 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).
