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...

Excluded iPAddress name constraints with an all-zero mask are not applied

An excludedsubtrees iPAddress name constraint with an all-zero mask 0.0.0.0/0 or ::/0 does not restrict iPAddress SANs in certificates issued beneath it. The mask check treated an all-zero mask as matching nothing, when a /0 prefix matches every address of its family, so the exclusion was silentl...
