CVE-2026-74727

A race condition in the Linux kernel's ovpn module (in-kernel OpenVPN) causes a Use-After-Free . When a peer is removed concurrently (via OVPN_CMD_PEER_DEL, keepalive expiry, or socket teardown) while ovpn_nl_peer_set_doit() or the float path (ovpn_peer_endpoints_update()) holds only a refcount, ...

CVE-2026-74726

A race condition in the Linux kernel's bonding module affects the Active-Backup Load Balancing (ALB) monitor (bond_alb_monitor() in drivers/net/bonding/bond_alb.c). The function reads primary_is_promisc under RCU, then drops RCU and acquires RTNL via rtnl_trylock(). In that window, the active sla...

CVE-2026-74715 bpf: Fix netns reference imbalance in conntrack kfuncs

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix netns reference imbalance in conntrack kfuncs The opts argument of the BPF conntrack kfuncs can point to a shared map value. bpfnfctlookup and bpfnfctallocentry read opts-netnsid separately when acquiring and releasing t...

CVE-2026-74714 bpf: tcp: Fix use-after-free in bpf_iter_tcp_established_batch()

In the Linux kernel, the following vulnerability has been resolved: bpf: tcp: Fix use-after-free in bpfitertcpestablishedbatch reqskqueuehashreq publishes a TCPNEWSYNRECV requestsock onto the ehash chain, drops the bucket lock, and only afterwards sets rskrefcnt to 3. Lockless readers such as...

CVE-2026-74714

A use-after-free vulnerability in the Linux kernel BPF TCP iterator, specifically in bpf_iter_tcp_established_batch(). The root cause is a race condition: sock_hold() increments the reference count of a request_sock whose rsk_refcnt is still zero at publish time, and the subsequent refcount_set(3...

CVE-2026-74709

CVE-2026-74709 affects the AF_XDP (xsk) subsystem in the Linux kernel. The root cause is that user space can modify metadata flags after a TX request has been processed; when the kernel rereads those flags during completion, it may write a timestamp into the metadata area that was never requested...

CVE-2026-74700

CVE-2026-74700 is a race condition in the Linux kernel's net/sched cls_api subsystem, specifically in the tc_new_tfilter function. An unlocked classifier's request can prematurely decrement the reference count of a locked classifier's protocol object without holding rtnl_lock, leading to a use-af...
