CVE-2026-3038

The CVE-2026-3038 issue is a FreeBSD routing socket bug in rtsock_msg_buffer() that can overflow a stack buffer on the stack, overwriting the canary and causing a kernel panic. It arises when a source sockaddr length is not validated, allowing unprivileged users to trigger a 127-byte overflow and...

CVE-2025-68670

CVE-2025-68670 affects xrdp and related components (e.g., xorgxrdp). The bug is an unauthenticated, stack-based buffer overflow caused by improper bounds checking when processing user domain information during the connection sequence. Exploitation could lead to remote code execution with network ...

CVE-2025-68670 xrdp improperly checks bounds of domain string length, which leads to Stack-based Buffer Overflow

xrdp is an open source RDP server. xrdp before v0.10.5 contains an unauthenticated stack-based buffer overflow vulnerability. The issue stems from improper bounds checking when processing user domain information during the connection sequence. If exploited, the vulnerability could allow remote...
