LIN1025-16063 : Security Advisory - linux - CVE-2026-53074

Created: Jun 25, 2026    Updated: Jul 31, 2026
Resolved Date: Jul 31, 2026
Found In Version: 10.25.33.2
Severity: Standard
Applicable for: Wind River Linux LTS 25
Component/s: Kernel

Description

In the Linux kernel, the following vulnerability has been resolved:  bpf: reject short IPv4/IPv6 inputs in bpf_prog_test_run_skb  bpf_prog_test_run_skb() calls eth_type_trans() first and then uses skb->protocol to initialize sk family and address fields for the test run.  For IPv4 and IPv6 packets, it may access ip_hdr(skb) or ipv6_hdr(skb) even when the provided test input only contains an Ethernet header.  Reject the input earlier if the Ethernet frame carries IPv4/IPv6 EtherType but the L3 header is too short.  Fold the IPv4/IPv6 header length checks into the existing protocol switch and return -EINVAL before accessing the network headers.
