Title
net: eswifi socket send payload length not bounded
Summary
The eswifi socket offload driver copies user-provided payloads into a fixed buffer without checking available space; oversized sends overflow `eswifi->buf`, corrupting kernel memory (CWE-120). Exploit requires local code that can call the socket send API; no remote attacker can reach it directly.
Severity ?
7.3 (High)
CWE
- CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
