In the Linux kernel, the following vulnerability has been resolved: ax25: properly unshare skbs in ax25kissrcv Bernard Pidoux reported a regression apparently caused by commit c353e8983e0d "net: introduce per netns packet chains". skb-dev becomes NULL and we crash in netifreceiveskbcore. Before...

CVE-2025-39856

CVE-2025-39856 concerns the Linux kernel network driver for TI am65 CPSW-NUSS (CPSW2G) where, in the TX completion path, the variable ndev may be accessed before initialization if no TX packets have been processed. This can cause a null pointer dereference and kernel crash. Affected component: ne...

CVE-2025-39851

CVE-2025-39851 relates to the Linux kernel VXLAN implementation. Affected scenario is when learning is enabled and an incoming packet attempts to refresh an FDB entry that points to an FDB nexthop group (not a remote destination). This could dereference a non-existent remote and trigger a NULL po...

CVE-2025-39848 ax25: properly unshare skbs in ax25_kiss_rcv()

In the Linux kernel, the following vulnerability has been resolved: ax25: properly unshare skbs in ax25kissrcv Bernard Pidoux reported a regression apparently caused by commit c353e8983e0d "net: introduce per netns packet chains". skb-dev becomes NULL and we crash in netifreceiveskbcore. Before...

CVE-2025-39848

CVE-2025-39848 affects the Linux kernel’s ax25_kiss_rcv() path. The root cause is queuing or mangling input skbs without verifying whether the skb is shared, which could trigger a crash in __netif_receive_skb_core() after a regression linked to per-netns packet chains. The description and connect...

CVE-2023-53439 net: skb_partial_csum_set() fix against transport header magic value

In the Linux kernel, the following vulnerability has been resolved: net: skbpartialcsumset fix against transport header magic value skb-transportheader uses the special 0xFFFF value to mark if the transport header was set or not. We must prevent callers to accidentaly set skb-transportheader to...

CVE-2023-53432

CVE-2023-53432 : Linux kernel vulnerability in the FireWire net path (firewire: net: fix use after free in fwnet_finish_incoming_packet()). The netif_rx() path frees the skb, so dereferencing skb->len could use freed memory. The incident is reported as resolved in the provided description; no ...

CVE-2022-50405

The CVE-2022-50405 entry describes a Linux kernel race in the vxlan path (net/tunnel) where deleting a vxlan device during packet reception can release a sock before sk_user_data readers finish. This leads to a NULL pointer dereference in vxlan_ecn_decapsulate() / vxlan_get_sk_family(). The repro...
