CVE-2026-97611
In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: fix use-after-free of the flow table mask array tblmaskarrayrealloc retires the old maskarray before it stops being reachable: old = ovsldereferencetbl-maskarray; if old ... callrcu&old-rcu, maskarrayrcucb;...
CVE-2026-97611
The Linux kernel contains a use-after-free vulnerability in the Open vSwitch component involving the flow table mask array. The issue exists in tbl_mask_array_realloc(), where call_rcu() is invoked to retire the old mask_array before it is no longer reachable. Because the pointer swap with rcu_as...
