0 CVE-2026-15923 is a denial-of-service vulnerability in the Zephyr project's SDIO subsystem. The issue arises when the SDIO card reports a maximum block size of zero, causing an infinite loop during data transfer operations. This loop occurs while holding a mutex, resulting in a permanent hang of the calling thread and denial of service to the SDIO peripheral and dependent subsystems. The vulnerability requires a malicious or malfunctioning SDIO card to be physically inserted. There is no impact on memory safety, confidentiality, or integrity, only availability. A fix is implemented that returns an error before entering the loop when the maximum block size is zero.
