Detailsinfo

A vulnerability, which was classified as problematic, was found in Linux Kernel up to 5.19.16/6.0.2. Affected is the function ssip_pn_open of the component HSI. The manipulation with an unknown input leads to a memory leak vulnerability. CWE is classifying the issue as CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. This is going to have an impact on availability. CVE summarizes:

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.

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2022-50708 since 12/24/2025. The exploitability is told to be difficult. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 279747 (Linux Distros Unpatched Vulnerability : CVE-2022-50708), which helps to determine the existence of the flaw in a target environment.
