Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The Linux kernel contains a memory leak in the nvme-core module, specifically within the dhchap secret store function. The issue involves failing to free the dhchap secret memory before returning, leading to a kernel memory leak. The backtrace indicates the leak occurs during a write operation via the kernfs fop write iter and vfs write functions, ultimately triggered by a system call. The leaked memory contains data related to 'DHHC-1:00:nxr5Kg' and 'uX4uoAxsJa4c/huL'.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
