+From: Andrew Lukoshko <alukoshko@almalinux.org>
+Subject: [PATCH AlmaLinux 10] rxrpc: linearize incoming DATA packet when it has paged frags
+
+AlmaLinux-specific backport of the intent of the upstream rxrpc fix
+posted at https://lore.kernel.org/all/afKV2zGR6rrelPC7@v4bel/
+(sibling to upstream commit f4c50a4034e6 in the ESP/xfrm subsystem).
+
+The upstream patch can not be cherry-picked against this 6.12 tree:
+its target lines were introduced by upstream commit d0d5c0cd1e71
+("rxrpc: Use skb_unshare() rather than skb_cow_data()") which is not
+present here. The age-equivalent code path on AlmaLinux 10 is the
+centralized skb_unshare() in net/rxrpc/io_thread.c that is run for
+every DATA packet with a non-zero securityIndex before in-place
+decryption.
+
+skb_unshare() only handles cloned skbs. An skb that is non-cloned but
+carries paged fragments (skb->data_len != 0) — e.g. pages attached via
+udp_sendpage() / splice() / MSG_SPLICE_PAGES on a UDP socket carrying
+rxrpc traffic — slips through and is decrypted in place over data the
+skb does not own privately. With kernel-modules-partner installed
+(rxrpc.ko enabled), this is exploitable.
+
+Replace the unconditional skb_unshare() with skb_copy() whenever the
+skb is cloned OR carries paged fragments. skb_copy() always returns a
+freshly allocated linear skb, so subsequent in-place decryption only
+touches kernel-owned memory. The original skb is consumed explicitly
+(skb_unshare did this internally via consume_skb()).
+
+Verified to apply with `patch -p1 -F0` (no offset, no fuzz, no
+rejects) against kernel-6.12.0-124.55.1.el10_1.
+
