PT-2026-79706

In the Linux kernel, the following vulnerability has been resolved: net/openvswitch: check Ethernet header length in key extract When a packet arrives on an ARPHRD NONE device e.g. TUN, ovs flow key extract trusts the user-provided skb-protocol field: if it is ETH P TEB, the packet is classified ...

CVE-2026-72296

A flaw was found in the Linux kernel's In-band Flow Engine IFE component. A remote attacker could send a specially crafted IFE frame with a malformed inner Ethernet header. This improper handling of the packet structure could lead to a system crash, resulting in a Denial of Service DoS...

CVE-2026-72296

In the Linux kernel, the following vulnerability has been resolved: net: ife: require ETHHLEN to be pullable in ifedecode ife decode may return after making only the outer IFE header and metadata pullable. The caller then passes the decapsulated packet to ethtypetrans, which expects the inner...

CVE-2026-72235

CVE-2026-72235 involves batman-adv in the Linux kernel. pskb_may_pull() in batadv_interface_rx() could realloc the buffer behind the skb, leaving pointers to the old buffer vulnerable to use-after-free. The issue was mitigated for the VLAN header but the ethernet header path used for TT and AP is...
