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

Description A potential memory leak has been identified in the Linux kernel, specifically in the nxp nci send() function. This function calls nxp nci i2c write() and only frees the skb when nxp nci i2c write() fails. However, even if nxp nci i2c write() succeeds, the skb is not freed, resulting in a memory leak. The nxp nci send() function should also free the skb when nxp nci i2c write() succeeds.

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