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

Description A resource leak was identified in the ssip pn open() function within the SSI protocol of the Linux kernel. Specifically, the function claims an HSI client's port using hsi claim port(). If hsi register port event() encounters an error and returns a negative value, the HSI client's port is not released using hsi release port(), leading to a potential resource leak. The issue is addressed by ensuring hsi release port() is called when hsi register port event() fails.

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