Description OSIDB Bzimport 2025-07-03 09:05:00 UTC 
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.
