VectorAV:L/AC:L/Au:S/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A memory leak was identified in the qla2xxx driver within the Linux kernel, specifically within the qla2x00 probe one() function. The issue occurs during adapter initialization when the base vha initialization fails. A memory allocation for scan.l within qla2x00 create host() is not released in the error handling path, leading to a memory leak. The leak was reported by kmemleak, with the unreferenced object size being 12288 bytes. The backtrace indicates the issue originates from the vmalloc node range, vmalloc node, vmalloc, qla2x00 create host, qla2x00 probe one, and local pci probe functions.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
