high Tenable Cloud Security Plugin ID 467108

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: virtio-net: fix len check in
 receive_big() receive_big() bounds the device-announced length by (big_packets_num_skbfrags + 1) *
 PAGE_SIZE. That is still too loose: add_recvbuf_big() sets sg[1] to start at offset sizeof(struct
 padded_vnet_hdr) into the first page, so the chain actually carries hdr_len + (PAGE_SIZE -
 sizeof(padded_vnet_hdr)) + big_packets_num_skbfrags * PAGE_SIZE bytes -- 20 bytes less than the check
 allows for the common hdr_len == 12 case. A malicious virtio backend can announce a len in that gap.
 page_to_skb() then walks one frag past the page chain, storing a NULL page->private into
 skb_shinfo()->frags[MAX_SKB_FRAGS], which is both an out-of-bounds write past the static frag array and a
 NULL frag handed up the rx path. Bound len by the size add_recvbuf_big() actually advertised.
 (CVE-2026-64552)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18613.675.37 or later.
