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 microchip-core-qspi SPI controller was resolved. The coreQSPI IP supports only a single chip select controlled automatically by hardware, but when multiple devices use GPIOs for chip selects, the built-in chip select may be incorrectly activated, causing conflicts. This issue was unnoticed because affected boards used GPIO chip selects exclusively. The vulnerability has been addressed in Linux kernel updates. The CVSS score is 5.5 (medium severity).

The Linux kernel's microchip-core-qspi SPI controller has a vulnerability where the built-in chip select (CS), which is automatically controlled by hardware for a single device, can be incorrectly asserted low when Linux attempts to access a device using GPIO-controlled chip selects. This causes the built-in CS to interfere with GPIO CS devices, potentially leading to hardware communication issues. The problem was undetected because boards with multiple SPI devices used only GPIO CS lines, avoiding reliance on the built-in CS. The issue is fixed in Linux kernel versions 7.0.0-28.28 and later variants as listed. The vulnerability has a CVSS 3.1 score of 5.5, indicating a medium severity impact with local attacker privileges and no user interaction required. The vendor advisory from Ubuntu confirms the availability of patches and recommends updating to fixed kernel versions.
