AI-suggested
An official patch is available and should be applied to affected Linux kernel versions to prevent the NULL pointer dereference. Users should update to the fixed kernel versions as provided by their Linux distribution vendors. No additional mitigation is required beyond applying the patch.
Description
A NULL pointer dereference vulnerability in the Linux kernel's TPS6594 PFSM driver was resolved by adding a NULL pointer check in the tps6594_pfsm_probe() function. The issue involved the potential for devm_kasprintf() to return NULL, which could lead to a NULL pointer dereference if unchecked. This vulnerability has a medium severity score and affects specific Linux kernel versions. A patch is available to address this issue.
