CVE-2026-90049
A flaw was found in the Linux kernel's networking subsystem. When the skbzerocopy function fails to orphan fragments, it incorrectly calls skbtxerror on the source skbuff skb. This premature completion of the zerocopy user argument and clearing of the SKBFLSHAREDFRAG flag can lead to a condition...

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.
