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

Description A use after free bug in the Linux kernel's NFC subsystem, specifically in the ndlc remove function, has been identified. This issue arises due to a race condition and affects both st nci i2c remove and st nci spi remove. The bug occurs when the st nci i2c remove function is called to remove the driver, and there is a sequence of events that leads to the use of ndlc->ndev after it has been freed. The issue is resolved by finishing the work before cleanup in ndlc remove.

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