| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: dsa: Fix possible memory leaks in dsa_loop_init()\n\nkmemleak reported memory leaks in dsa_loop_init():\n\nkmemleak: 12 new suspected memory leaks\n\nunreferenced object 0xffff8880138ce000 (size 2048):\n comm \"modprobe\", pid 390, jiffies 4295040478 (age 238.976s)\n backtrace:\n [<000000006a94f1d5>] kmalloc_trace+0x26/0x60\n [<00000000a9c44622>] phy_device_create+0x5d/0x970\n [<00000000d0ee2afc>] get_phy_device+0xf3/0x2b0\n [<00000000dca0c71f>] __fixed_phy_register.part.0+0x92/0x4e0\n [<000000008a834798>] fixed_phy_register+0x84/0xb0\n [<0000000055223fcb>] dsa_loop_init+0xa9/0x116 [dsa_loop]\n ...\n\nThere are two reasons for memleak in dsa_loop_init().\n\nFirst, fixed_phy_register() create and register phy_device:\n\nfixed_phy_register()\n get_phy_device()\n phy_device_create() # freed by phy_device_free()\n phy_device_register() # freed by phy_device_remove()\n\nBut fixed_phy_unregister() only calls phy_device_remove().\nSo the memory allocated in phy_device_create() is leaked.\n\nSecond, when mdio_driver_register() fail in dsa_loop_init(),\nit just returns and there is no cleanup for phydevs.\n\nFix the problems by catching the error of mdio_driver_register()\nin dsa_loop_init(), then calling both fixed_phy_unregister() and\nphy_device_free() to release phydevs.\nAlso add a function for phydevs cleanup to avoid duplacate." |
