Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved. The issue was related to the zynqmp audio init() function, where devm kasprintf() calls could return null pointers on failure, but some return values were not checked. This could lead to referencing null pointers in subsequent code. The fix involves adding a NULL check in zynqmp audio init() to avoid this issue.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
