Description OSIDB Bzimport 2025-12-24 12:07:04 UTC 
In the Linux kernel, the following vulnerability has been resolved:

HSI: ssi_protocol: fix potential resource leak in ssip_pn_open()

ssip_pn_open() claims the HSI client's port with hsi_claim_port(). When
hsi_register_port_event() gets some error and returns a negetive value,
the HSI client's port should be released with hsi_release_port().

Fix it by calling hsi_release_port() when hsi_register_port_event() fails.
