  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: liquidio: Fix off-by-one error in PF setup_nic_devices() cleanup\n\nIn setup_nic_devices(), the initialization loop jumps to the label\nsetup_nic_dev_free on failure. The current cleanup loop while(i--)\nskip the failing index i, causing a memory leak.\n\nFix this by changing the loop to iterate from the current index i\ndown to 0.\n\nAlso, decrement i in the devlink_alloc failure path to point to the\nlast successfully allocated index.\n\nCompile tested only. Issue found using code review.",
