VULNERABILITIES

CVE-2026-99045 Details

Description

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.
