AI-suggested

A fix is available for this vulnerability. Users should apply the updated Linux kernel versions that include the added allocation failure check in the ASoC SDCA component. No additional mitigation is required beyond applying the official patch.

Description

A vulnerability in the Linux kernel's ASoC SDCA component was fixed by adding a missing allocation failure check for the Entity name string. The function find_sdca_entity_iot() previously allocated memory for the Entity name without verifying if the allocation succeeded, which could lead to a failure scenario. This issue has been resolved by adding a NULL check after the allocation.
