Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel up to 5.4.250/5.10.187/5.15.120/6.1.39/6.4.4. This affects the function svc_create_memory_pool of the component stratix10-svc. 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 confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: firmware: stratix10-svc: Fix a potential resource leak in svc_create_memory_pool() svc_create_memory_pool() is only called from stratix10_svc_drv_probe(). Most of resources in the probe are managed, but not this memremap() call. There is also no memunmap() call in the file. So switch to devm_memremap() to avoid a resource leak.

It is possible to read the advisory at git.kernel.org. This vulnerability is uniquely identified as CVE-2023-53255 since 09/15/2025. Technical details of the vulnerability are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 265165 (Linux Distros Unpatched Vulnerability : CVE-2023-53255), which helps to determine the existence of the flaw in a target environment.
