UBUNTU-CVE-2025-40290

In the Linux kernel, the following vulnerability has been resolved: xsk: avoid data corruption on cq descriptor number Since commit 30f241fcf52a "xsk: Fix immature cq descriptor production", the descriptor number is stored in skb control block and xskcqsubmitaddrlocked relies on it to put the ume...

CVE-2025-40301

The CVE-2025-40301 issue concerns the Linux kernel Bluetooth stack. In hci_cmd_complete_evt(), when an unknown command opcode is reported, the code may treat the first byte of remaining skb->data as the return status. If parameters were already pulled in hci_event_func(), skb may be empty, cau...

CVE-2025-40240

The CVE CVE-2025-40240 is a Linux kernel SCTP vulnerability. The issue was a NULL dereference when processing a chunk data buffer that is missing; chunk->skb could be dereferenced in the if-block intended to handle NULL, unless frag_list is checked and the replacement of chunk->skb occurs j...

kernel: net: usb: smsc75xx: Limit packet length to skb->len

In the Linux kernel, the following vulnerability has been resolved: net: usb: smsc75xx: Limit packet length to skb-len Packet length retrieved from skb data may be larger than the actual socket buffer length up to 9026 bytes. In such case the cloned skb passed up the network stack will leak kerne...
