In the Linux kernel, the following vulnerability has been resolved:
net: liquidio: Fix off-by-one error in VF 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.
Compile tested only. Issue found using code review.

CVE-2026-23256 [MEDIUM] CVE-2026-23256 kernel: net: liquidio: Fix off-by-one error in VF setup_nic_devices() cleanup
CVE-2026-23256 kernel: net: liquidio: Fix off-by-one error in VF setup_nic_devices() cleanup
In the Linux kernel, the following vulnerability has been resolved:
net: liquidio: Fix off-by-one error in VF 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.
Compile tested only. Issue found using code review.
