CVE Database V5

AlienVault OTX General

Real-world exploitation and exposure telemetry from the OffSeq Mirage honeypot fleet and Sonar internet scans — which CVEs attackers are actually exploiting and which are exposed in the wild, plus attacker IoCs. All IPs are masked; no raw victim or sensor identity is ever published.

A vulnerability in the Linux kernel's AMD display driver (drm/amd/display) could cause a NULL pointer dereference leading to a system crash. The issue occurs in error handling paths where a NULL check is improperly implemented, causing the logging function to dereference a NULL pointer. This flaw has been fixed by adjusting the NULL checks to prevent the crash. The vulnerability affects multiple Linux kernel versions prior to 7.0.0-28.28 and related builds. A patch is available and should be applied to mitigate the issue.

The Linux kernel contained a vulnerability in the drm/amd/display subsystem where error handling functions dc_dmub_srv_log_diagnostic_data() and dc_dmub_srv_enable_dpia_trace() performed NULL checks incorrectly. They checked if dc_dmub_srv or dc_dmub_srv->dmub were NULL and then called DC_LOG_ERROR(), which internally uses dc_dmub_srv->ctx. If dc_dmub_srv was NULL, this led to a NULL pointer dereference and a kernel crash. The fix splits the NULL checks to first return immediately if dc_dmub_srv is NULL, then log errors only if dc_dmub_srv is valid. This vulnerability is tracked as CVE-2026-53313 and affects Linux kernel versions prior to 7.0.0-28.28 and related variants.
