CVE-2026-64077 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libperf package and not the libperf package as distributed by RHEL.
In the Linux kernel, the following vulnerability has been resolved:
netfilter: ebtables: move to two-stage removal scheme
Like previous patches for x_tables, follow same pattern in ebtables. We can't reuse xt helpers: ebt_table struct layout is incompatible.
table->ops assignment is now done while still holding the ebt mutex to make sure we never expose partially-filled table struct.
