Description
In the Linux kernel, the following vulnerability has been resolved:
net: liquidio: Fix off-by-one error in PF setup_nic_devices() cleanup
In setup_nic_devices(), the initialization loop jumps to the label setup_nic_dev_free on failure. The current cleanup loop while(i--) skip the failing index i, causing a memory leak.
Fix this by changing the loop to iterate from the current index i down to 0.
Also, decrement i in the devlink_alloc failure path to point to the last successfully allocated index.
Compile tested only. Issue found using code review.
