H2O Vulnerable to Denial of Service (DoS) via `/3/ImportFiles` Endpoint

A vulnerability in the /3/ImportFiles endpoint of h2oai/h2o-3 version 3.46.1 allows an attacker to cause a denial of service. The endpoint takes a single GET parameter, path, which can be recursively set to reference itself. This leads the server to repeatedly call its own endpoint, eventually...

Vulnerability of the mhi_queue() function in the drivers/bus/mhi/core/main.c module – The MHI bus driver in the Linux kernel allows a hacker to cause a service failure.

Vulnerability of the mhiqueue function in the drivers/bus/mhi/core/main.c module – The MHI driver in the Linux kernel is vulnerable due to the repeated use of previously freed memory. Exploiting this vulnerability can allow an attacker to cause a service failure...
