medium Tenable Self-Hosted Container Security Plugin ID 468850

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: bpf: Check skb->transport_header is
 set in bpf_skb_check_mtu The bpf_skb_check_mtu helper needs to use skb->transport_header when the
 BPF_MTU_CHK_SEGS flag is used: bpf_skb_check_mtu(skb, ifindex, &mtu_len, 0, BPF_MTU_CHK_SEGS) The
 transport_header is not always set. There is a WARN_ON_ONCE report when CONFIG_DEBUG_NET is enabled +
 skb->gso_size is set + bpf_prog_test_run is used: WARNING: CPU: 1 PID: 2216 at
 ./include/linux/skbuff.h:3071 skb_gso_validate_network_len bpf_skb_check_mtu
 bpf_prog_3920e25740a41171_tc_chk_segs_flag # A test in the next patch bpf_test_run bpf_prog_test_run_skb
 For a normal ingress skb (not test_run), skb_reset_transport_header is performed but there is plan to
 avoid setting it as described in commit 2170a1f09148 ("net: no longer reset transport_header in
 __netif_receive_skb_core()"). This patch fixes the bpf helper by checking skb_transport_header_was_set().
 The check is done just before skb->transport_header is used, to avoid breaking the existing bpf prog. The
 WARN_ON_ONCE is limited to bpf_prog_test_run, so targeting bpf-next. (CVE-2025-68363)

Solution

Update the sys-kernel/csql-kernel-6_12 library and its related packages to version 19216.104.113 or later.
