CVE-2026-74695

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfflowtable: drop existing skb dst before skbdstsetnoref Incoming skbs passing through netfilter flowtable offload hooks or XFRM offload path might already carry a ref-counted dstentry assigned during earlier RX or...

CVE-2026-74695 netfilter: nf_flow_table: drop existing skb dst before skb_dst_set_noref()

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfflowtable: drop existing skb dst before skbdstsetnoref Incoming skbs passing through netfilter flowtable offload hooks or XFRM offload path might already carry a ref-counted dstentry assigned during earlier RX or...

CVE-2026-74543

A flaw was found in the Linux kernel's UDP tunnel network interface controller NIC offload code. When a device registration fails, the system may not properly unregister the NIC tunnel, leading to a permanent memory leak. This can result in resource exhaustion over time, potentially causing a...

CVE-2026-72365

A flaw was found in the netfs component of the Linux kernel. This vulnerability arises from incorrect handling of NETFSRREQOFFLOADCOLLECTION during writethrough operations. This issue could lead to asynchronous OSYNC writes not being properly collected, potentially resulting in data inconsistency...

kernel: netfilter: flowtable: strictly check for maximum number of actions

A flaw was found in the Netfilter flowtable component of the Linux kernel. This vulnerability occurs because the system does not strictly check the maximum number of hardware offload actions for IPv6, allowing it to process more actions than supported. This could potentially lead to system...

EUVD-2026-62339

After dispatching a decrypt operation to OCF and receiving the result, the wg4 driver failed to check whether the MAC verification step succeeded. The driver thus silently accepted packets with an invalid Poly1305 authentication tag. A remote attacker who can send UDP packets to a WireGuard...

CVE-2026-72338

In the Linux kernel, the following vulnerability has been resolved: net/sched: actpedit: fix TOCTOU heap OOB write in tc offload There is a TOCTOU race condition in flower lockless approach between sizing a flowrule buffer and filling it. [email protected] reports: The clsflower...

UBUNTU-CVE-2026-72365

In the Linux kernel, the following vulnerability has been resolved: netfs: Fix writethrough to use collection offload Fix writethrough write to set NETFSRREQOFFLOADCOLLECTION on the request so that collection is processed asynchronously rather than only right at the end - and also so that...

CVE-2026-74382

CVE-2026-74382 concerns a stack overflow in the Linux kernel’s net/sched cls_bpf offload rollback. The issue arises when cls_bpf_offload_cmd() recursively re-enters during rollback if tc_setup_cb_replace() fails twice in a row, allowing unbounded recursion until the stack is exhausted. Two propos...

CVE-2026-74382 net/sched: cls_bpf: prevent unbounded recursion in offload rollback

In the Linux kernel, the following vulnerability has been resolved: net/sched: clsbpf: prevent unbounded recursion in offload rollback Quan Sun reported 1 a stack overflow in clsbpfoffloadcmd. Reproducer on netdevsim: add a skipsw clsbpf filter, set the bpftcaccept debugfs knob to 0, then tc filt...

CVE-2026-72365

CVE-2026-72365 affects the Linux kernel netfs subsystem. The vulnerability was addressed by a fix to writethrough handling: the write request now sets NETFS_RREQ_OFFLOAD_COLLECTION so collection is processed asynchronously (not only at the end) and asynchronous O_SYNC writes are collected as well...
