high Tenable Cloud Security Plugin ID 472111

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: netfilter: handle unreadable frags
sashiko reports: When an skb with unreadable fragments (such as from devmem TCP, where
skb_frags_readable(skb) returns false) is processed by the u32 module, skb_copy_bits() will safely return
a negative error code [..] xt_u32: bail out with hotdrop in this case. gather_frags: return -1, just as if
we had no fragment header. nfnetlink_queue: restrict to the linear part. nfnetlink_log: restrict to the
linear part. v2: - skb_zerocopy helpers don't copy readable flag, i.e. nfnetlink_queue is broken too
xt_u32 shouldn't return true if hotdrop was set. (CVE-2026-64414)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.299.82 or later.
