high Tenable Cloud Security Plugin ID 467361

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: net: skbuff: preserve shared-frag
 marker during coalescing skb_try_coalesce() can attach paged frags from @from to @to. If @from has
 SKBFL_SHARED_FRAG set, the resulting @to skb can contain the same externally-owned or page-cache-backed
 frags, but the shared-frag marker is currently lost. That breaks the invariant relied on by later in-place
 writers. In particular, ESP input checks skb_has_shared_frag() before deciding whether an uncloned
 nonlinear skb can skip skb_cow_data(). If TCP receive coalescing has moved shared frags into an unmarked
 skb, ESP can see skb_has_shared_frag() as false and decrypt in place over page-cache backed frags.
 Propagate SKBFL_SHARED_FRAG when skb_try_coalesce() transfers paged frags. The tailroom copy path does not
 need the marker because it copies bytes into @to's linear data rather than transferring frag descriptors.
 (CVE-2026-46300)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.381.161 or later.
