CVE-2026-98955

The Linux kernel contains a vulnerability in the __skb_flow_dissect() function where key_control->thoff is computed using min_t(u16, ...). This causes a u16 truncation of skb->len; if skb->len modulo 65536 is smaller than nhoff, thoff is set to a bogus small value . This can lead callers...

CVE-2023-53125: Missing Release of Memory after Effective Lifetime

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...
