In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix memory leak in qla2x00_probe_one() There is a memory leak reported by kmemleak: unreferenced object 0xffffc900003f0000 (size 12288): comm "modprobe", pid 19117, jiffies 4299751452 (age 42490.264s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [] __vmalloc_node_range+0xe56/0x1110 [] __vmalloc_node+0xbd/0x150 [] vmalloc+0x25/0x30 [] qla2x00_create_host+0x7a0/0xe30 [qla2xxx] [] qla2x00_probe_one+0x2eb8/0xd160 [qla2xxx] [] local_pci_probe+0xeb/0x1a0 The root cause is traced to an error-handling path in qla2x00_probe_one() when the adapter "base_vha" initialize failed. The fab_scan_rp "scan.l" is used to record the port information and it is allocated in qla2x00_create_host(). However, it is not released in the error handling path "probe_failed". Fix this by freeing the memory of "scan.l" when an error occurs in the adapter initialization process.
