Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
xfrm: iptfs: preserve shared-frag marker in iptfs_consume_frags()<br />
<br />
iptfs_consume_frags() transfers paged fragments from one socket buffer<br />
to another but fails to propagate the SKBFL_SHARED_FRAG flag. This is<br />
the same class of bug that was fixed in skb_try_coalesce() for<br />
CVE-2026-46300: when fragments backed by read-only page-cache pages are<br />
merged, the marker indicating their shared nature must be preserved so<br />
that ESP can decide correctly whether in-place encryption is safe.<br />
<br />
Apply the same two-line fix used in skb_try_coalesce() to<br />
iptfs_consume_frags().
