About this tag
The tag 'ti udma' covers discussions about the Texas Instruments UDMA (Universal DMA) engine driver in the Linux kernel, particularly in the context of security vulnerabilities and enterprise Linux distributions. A recent thread addresses CVE-2025-38138, a robustness fix in the TI UDMA driver where the probe routine lacked a NULL check for devm_kasprintf(), potentially causing a crash on memory allocation failure. The fix adds a simple NULL check. The thread also discusses Microsoft's Azure Linux attestation for this vulnerability, clarifying that the attestation is product-scoped and does not guarantee safety for other Microsoft-supplied kernels or images. This tag is relevant for Linux kernel developers, system administrators, and security professionals working with TI hardware or Azure Linux.

Upstream maintainers fixed the bug by inserting a simple...
