  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: lan743x: Initialize eth_syslock spinlock before use\n\nlan743x_hardware_init() calls pci11x1x_strap_get_status() during the\nPCI11x1x probe sequence. That helper acquires the Ethernet subsystem\nhardware lock via lan743x_hs_syslock_acquire(), which relies on\nadapter-\u003eeth_syslock_spinlock to serialize access.\n\nThe spinlock is currently initialized only after the strap status is\nread. With CONFIG_DEBUG_SPINLOCK enabled, taking the zeroed initialized\nspinlock can trip the spinlock debug check.\n\nFix by initializing adapter-\u003eeth_syslock_spinlock before reading the\nstrap status so the probe path never attempts to lock an uninitialized\nspinlock.",
