CVE-2025-38138 Details
Description
In the Linux kernel, the following vulnerability has been resolved: dmaengine: ti: Add NULL check in udma_probe() devm_kasprintf() returns NULL when memory allocation fails. Currently, udma_probe() does not check for this case, which results in a NULL pointer dereference. Add NULL check after devm_kasprintf() to prevent this issue.
A NULL pointer dereference vulnerability has been identified in the Linux kernel's DMA engine component for Texas Instruments (TI). The issue arises in the 'udma_probe()' function, which fails to validate the output of 'devm_kasprintf()' before using it. This oversight can lead to a NULL pointer dereference when memory allocation by 'devm_kasprintf()' fails. The vulnerability has been addressed by adding a NULL check after the 'devm_kasprintf()' call to prevent such dereferences.
