CVE-2026-80588
Description
AI Translation Available
In the Linux kernel, the following vulnerability has been resolved:
mptcp: reclaim forward-allocated memory on RX path errors
After commit 9db5b3cec4ec ('mptcp: borrow forward memory from subflow'),
errors in the receive path prior to queueing skbs into the receive
queue do not trigger forward-allocated memory reclaiming.
Prevent forward memory from growing unboundedly in pathological drop
scenarios by explicitly reclaiming memory when skbs are dropped.
