CVE-2025-40183

CVE-2025-40183 reflects a Linux kernel bug in BPF: metadata_dst leak via __bpf_redirect_neigh_v{4,6}. In workloads using Cilium’s BPF egress gateway, vxLAN-decapsulated traffic was routed with bpf_redirect_neigh(), which could leave behind a metadata_dst object attached to the skb and not release...

kernel: skbuff: skb_segment, Call zero copy functions before using skbuff frags

In the Linux kernel, the following vulnerability has been resolved: skbuff: skbsegment, Call zero copy functions before using skbuff frags Commit bf5c25d60861 "skbuff: in skbsegment, call zerocopy functions once per nskb" added the call to zero copy functions in skbsegment. The change introduced ...

kernel: vsock/virtio: Validate length in packet header before skb_put()

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: Validate length in packet header before skbput When receiving a vsock packet in the guest, only the virtqueue buffer size is validated prior to virtiovsockskbrxput. Unfortunately, virtiovsockskbrxput uses the length...

EUVD-2025-124908

In the Linux kernel, the following vulnerability has been resolved: idpf: cleanup remaining SKBs in PTP flows When the driver requests Tx timestamp value, one of the first steps is to clone SKB using skbget. It increases the reference counter for that SKB to prevent unexpected freeing by another...

EUVD-2025-124934

In the Linux kernel, the following vulnerability has been resolved: tls: Use skdstget and dstdevrcu in getnetdevforsock. getnetdevforsock is called during setsockopt, so not under RCU. Using skdstgetsk-dev could trigger UAF. Let's use skdstget and dstdevrcu. Note that the only -ndoskgetlowerdev...

kernel: sunrpc: fix client side handling of tls alerts

In the Linux kernel, the following vulnerability has been resolved: sunrpc: fix client side handling of tls alerts A security exploit was discovered in NFS over TLS in tlsalertrecv due to its assumption that there is valid data in the msghdr's iterator's kvec. Instead, this patch proposes the...

UBUNTU-CVE-2025-40175

In the Linux kernel, the following vulnerability has been resolved: idpf: cleanup remaining SKBs in PTP flows When the driver requests Tx timestamp value, one of the first steps is to clone SKB using skbget. It increases the reference counter for that SKB to prevent unexpected freeing by another...

UBUNTU-CVE-2025-40176

In the Linux kernel, the following vulnerability has been resolved: tls: wait for pending async decryptions if tlsstrpmsghold fails Async decryption calls tlsstrpmsghold to create a clone of the input skb to hold references to the memory it uses. If we fail to allocate that clone, proceeding with...

CVE-2025-40175

CVE-2025-40175 affects the Linux kernel driver for idpf in PTP timestamping. The issue arises when cloning an SKB (skb_get) to latch a Tx timestamp: the K/U may increment the SKB refcount, and under certain conditions the SKB is assigned but not consumed in PTP flows (e.g., due to a reset during ...

CVE-2025-40168

CVE-2025-40168 : In the Linux kernel, smc_clc_prfx_match() was using sk_dst_get(sk)->dev, which could trigger a use-after-free since smc_listen_work() is not under RCU/RTNL. The fix switches to __sk_dst_get() and dst_dev_rcu() to safely obtain the device. Note: the function’s return value is n...

CVE-2025-40149

CVE-2025-40149 affects the Linux kernel TLS path: get_netdev_for_sock() could trigger a use-after-free if sk_dst_get(sk)->dev is used during setsockopt(). The fix replaces sk_dst_get() with __sk_dst_get() and dst_dev_rcu() in get_netdev_for_sock(), and notes that the only user of ->ndo_sk_g...
