CVE-2026-64044 ovpn: respect peer refcount in CMD_NEW_PEER error path

In the Linux kernel, the following vulnerability has been resolved: ovpn: respect peer refcount in CMDNEWPEER error path ovpnnlpeernewdoit's error path calls ovpnpeerrelease directly rather than ovpnpeerput, bypassing the kref. The accompanying comment "peer was not yet hashed, thus it is not use...

CVE-2026-64024

CVE-2026-64024 concerns a Linux kernel issue where a per-CPU tcp_tw_isn leak could enable ISN prediction. The root cause was that TIME_WAIT-derived ISNs were stored in a per-CPU variable and could be consumed by a subsequent SYN if a packet was dropped along several paths (e.g., min_ttl/min_hop, ...

CVE-2026-64007

The CVE concerns the Linux kernel netfilter synproxy path. In synproxy_tstamp_adjust, the code rewrites the TCP timestamp in place and then updates the TCP checksum via inet_proto_csum_replace4() on a caller-supplied tcphdr pointer. Between retrieving the pointer (via skb_header_pointer) and use,...
