DEBIAN-CVE-2026-64046

In the Linux kernel, the following vulnerability has been resolved:  net: tls: prevent chain-after-chain in plain text SG  Sashiko points out that if end = 0 (start != 0) the current code will create a chain link to content type right after the wrap link:    This would create a chain where the wrap link points directly   to another chain link. The scatterlist API sg_next iterator   does not recursively resolve consecutive chain links.  meaning this is illegal input to crypto.  The wrapping link is unnecessary if end = 0. end is the entry after the last one used so end = 0 means there's nothing pushed after the wrap:     end         start            i     v            v              v   [   ]...[   ][ d ][ d ][ d ][ d ][rsv for wrap]  Skip the wrapping in this case.  TLS 1.3 can use the "wrapping slot" for it's chaining if end = 0. This avoids the chain-after-chain.  Move the wrap chaining before marking END and chaining off content type, that feels like more logical ordering to me, but should not matter from functional perspective.
