Positive Technologies (AI Summary)

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

Description The Linux kernel contains a reference count leak in the rcar fdp1 module, specifically within the probe and remove functions. The rcar fcp get() function acquires a reference that is not properly released using rcar fcp put(). This issue is addressed by adding the missing rcar fcp put() call in fdp1 remove and the error paths of fdp1 probe().

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