CVE-2026-80793 ipv4: reject undersized MTUs in ip_do_fragment()

In the Linux kernel, the following vulnerability has been resolved: ipv4: reject undersized MTUs in ipdofragment ipdofragment subtracts the IPv4 header length from the effective MTU and passes the resulting payload MTU to ipfragnext. If the effective MTU is smaller than hlen + 8, ipfragnext round...

kernel: ipv4: free net->ipv4.sysctl_local_reserved_ports after unregister_net_sysctl_table()

A flaw was found in the Linux kernel's IPv4 networking component. The ipv4sysctlexitnet function prematurely frees the net-ipv4.sysctllocalreservedports memory. This can lead to a use-after-free vulnerability, where other threads might attempt to access deallocated memory. Such an issue can resul...

CVE-2021-44320

Parrot AR.Drone versions 1 and 2 are susceptible to denial-of-service (DoS) attacks because they lack adequate mechanisms to prevent them.
