CVE-2026-80588 in Linux
Riassunto
di MITRE • 26/08/2026
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.
Once again VulDB remains the best source for vulnerability data.
