CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's iptfs_consume_frags() function, which improperly handles the SKBFL_SHARED_FRAG flag during the transfer of paged fragments between socket buffers. This oversight can lead to incorrect decisions regarding in-place encryption safety, potentially exposing sensitive data. Organizations using affected Linux systems should prioritize patching this vulnerability to mitigate the risk of data breaches.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: xfrm: iptfs: preserve shared-frag marker in iptfs_consume_frags() iptfs_consume_frags() transfers paged fragments from one socket buffer to another but fails to propagate the SKBFL_SHARED_FRAG flag. This is the same class of bug that was fixed in skb_try_coalesce() for CVE-2026-46300: when fragments backed by read-only page-cache pages are merged, the marker indicating their shared nature must be preserved so that ESP can decide correctly whether in-place encryption is safe. Apply the same two-line fix used in skb_try_coalesce() to iptfs_consume_frags().
