"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: phy: clear phydev->devlink when the link is deleted\n\nThere is a potential crash issue when disabling and re-enabling the\nnetwork port. When disabling the network port, phy_detach() calls\ndevice_link_del() to remove the device link, but it does not clear\nphydev->devlink, so phydev->devlink is not a NULL pointer. Then the\nnetwork port is re-enabled, but if phy_attach_direct() fails before\ncalling device_link_add(), the code jumps to the \"error\" label and\ncalls phy_detach(). Since phydev->devlink retains the old value from\nthe previous attach/detach cycle, device_link_del() uses the old value,\nwhich accesses a NULL pointer and causes a crash. The simplified crash\nlog is as follows.\n\n[ 24.702421] Call trace:\n[ 24.704856] device_link_put_kref+0x20/0x120\n[ 24.709124] device_link_del+0x30/0x48\n[ 24.712864] phy_detach+0x24/0x168\n[ 24.716261] phy_attach_direct+0x168/0x3a4\n[ 24.720352] phylink_fwnode_phy_connect+0xc8/0x14c\n[ 24.725140] phylink_of_phy_connect+0x1c/0x34\n\nTherefore, phydev->devlink needs to be cleared when the device link is\ndeleted."
