CVE-2026-74662

CVE-2026-74662 is a race condition in the Linux kernel IP fragment reassembly path (inet: frags). The function inet_frag_create() arms the fragment queue timer before inserting the queue into the fqdir rhashtable. When the namespace fragment timeout is zero or negative, the timer can fire before ...

CVE-2026-65623 Quadratic CPU blow-up reassembling fragmented WebSocket messages in Bandit

Inefficient Algorithmic Complexity vulnerability in mtrudel bandit allows unauthenticated remote denial of service via CPU exhaustion during WebSocket fragment reassembly. The size guard 'Elixir.Bandit.WebSocket.Connection':oversizemessage?/2 called from handleframe/3 in...

CVE-2026-65623

CVE-2026-65623 describes a Quadratic CPU blow-up in Bandit’s WebSocket message reassembly. The vulnerability arises when handling fragmented WebSocket frames: each non-final continuation frame is appended to a left-nested iolist and the entire buffer is re-measured with IO.iodata_length/1 on ever...

SUSE CVE-2026-63915

In the Linux kernel, the following vulnerability has been resolved: nfc: hci: fix out-of-bounds read in HCP header parsing Both nfchcirecvfromllc and ncihcidatareceivedcb read packet-header from skb-data at function entry without first checking that the buffer holds at least one byte. A malicious...

CVE-2026-64055

A flaw was found in the Linux kernel's Cortina ethernet driver. When the network interface processes incoming packets, a counter used for reassembling fragmented packets can be prematurely reset. This can lead to incomplete packet reassembly, potentially causing network communication issues or...

CVE-2026-63090

ProFTPD before 1.3.9c and 1.3.10rc3 contains a heap-based buffer overflow vulnerability in the modsftp module that allows authenticated low-privilege attackers to achieve arbitrary code execution by sending crafted SFTP packet fragments exceeding the 16 KB reassembly buffer in the fxp.c component...

CVE-2026-15813

A vulnerability was found in the network packet de-fragmentation engine of kronosnet Version affected = 1.34. The internal reassembly code does not properly validate sequence numbers of incoming payload fragments. An attacker can exploit this lack of verification by transmitting malformed packets...
