CVE-2026-99045
In the Linux kernel, the following vulnerability has been resolved: ibmveth: h_free logical LAN on open-fail after register ibmveth_open() registers the logic
In the Linux kernel, the following vulnerability has been resolved:
ibmveth: h_free logical LAN on open-fail after register
ibmveth_open() registers the logical LAN, then allocates the RX
buffer pools. A pool failure jumps to out_free_buffer_pools without
h_free_logical_lan(), so PHYP still owns the buffer-list page when
it is unmapped. request_irq() failure already issued the hypercall
before taking the same label.
Move that h_free to the shared post-register unwind so both paths
deregister before the buffer list is unmapped.
