Doc Text:	A flaw was found in the Linux kernel's ASoC (Advanced Linux Sound Architecture System on Chip) SDCA (SoundWire Digital Control Adapter) component. The `find_sdca_entity_iot()` function fails to check for successful memory allocation when assigning an entity name. This vulnerability could allow a local attacker to cause a denial of service, leading to system instability or a crash.	Story Points:	---

Description OSIDB Bzimport 2026-03-25 11:05:29 UTC

In the Linux kernel, the following vulnerability has been resolved:

ASoC: SDCA: Add allocation failure check for Entity name

Currently find_sdca_entity_iot() can allocate a string for the
Entity name but it doesn't check if that allocation succeeded.
Add the missing NULL check after the allocation.
