CVE-2026-90049

CVE-2026-90049 is a Linux kernel vulnerability in skb_zerocopy() (net/skbuff). On an skb_orphan_frags() failure, the function calls skb_tx_error() on the source skb it does not own, prematurely completing the zerocopy uarg and clearing the SKBFL_SHARED_FRAG page-ownership flag. On Open vSwitch's ...

CVE-2026-80977

A flaw was found in the Linux kernel's networking subsystem. The skbtxerror function improperly handles shared zerocopy state in socket buffers skbs. When a cloned skb is processed, it can prematurely signal that its pages are free and drop shared fragment flags while the original skb is still in...
