critical Tenable Cloud Security Plugin ID 467147

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: vxlan: use pskb_network_may_pull() in
 route_shortcircuit() route_shortcircuit() currently calls pskb_may_pull(skb, sizeof(struct iphdr)) (or
 ipv6hdr), which checks if bytes are available starting from skb->data. However, in vxlan_xmit(), skb->data
 points to the MAC header, so skb_network_offset(skb) is ETH_HLEN (14 bytes). Using pskb_may_pull(skb, 20)
 only checks 20 bytes from skb->data (which is 14 bytes MAC header + 6 bytes of IP header), leaving the
 rest of the IP header potentially un-pulled in non-linear frags. Subsequent dereferences of
 ip_hdr(skb)->daddr can read beyond the pulled linear buffer length. Fix this by using
 pskb_network_may_pull(), which adds skb_network_offset(skb) to the length check to ensure the full network
 header is present in the linear buffer. (CVE-2026-74473)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.584.3 or later.
