CVE-2026-71971 U-Boot before 2026.10-rc3 Out-of-Bounds Write in IP Fragment Reassembly

U-Boot before 2026.10-rc3 with CONFIGIPDEFRAG enabled contains an out-of-bounds write vulnerability in the netdefragment function in net/net.c. Remote attackers can send a crafted IP fragment with non-zero offset and More-Fragments flag set during netboot to corrupt adjacent memory and crash the...

CVE-2026-71971

The U-Boot bootloader (versions before 2026.10-rc3 ) is vulnerable to an out-of-bounds write in the ‘net_defragment‘ function within net/net.c when CONFIG_IP_DEFRAG is enabled. A remote attacker can trigger this by sending a crafted IP fragment with a non-zero offset and the More-Fragments flag s...

kernel: IP fragments with random offsets allow a remote denial of service (FragmentSmack)

A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment reassembly algorithm by sending specially crafted packets which could lead to a CPU...

kernel: a bug in ip_frag_reasm() can cause a crash in ip_do_fragment()

A security flaw was found in the ipfragreasm function in net/ipv4/ipfragment.c in the Linux kernel which can cause a later system crash in ipdofragment. With certain non-default, but non-rare, configuration of a victim host, an attacker can trigger this crash remotely, thus leading to a remote...

FreeBSD : FreeBSD -- Resource exhaustion in IP fragment reassembly (359e1548-a652-11e8-805b-a4badb2f4699)

A researcher has notified us of a DoS attack applicable to another operating system. While FreeBSD may not be vulnerable to that exact attack, we have identified several places where inadequate DoS protection could allow an attacker to consume system resources. It is not necessary that the attack...
