CVE-2026-46323
In the Linux kernel, the following vulnerability has been resolved: net: gro: don't merge zcopy skbs skbgroreceive can currently copy frags between the source and GRO skb, without checking the zerocopy status, and in particular the SKBFLMANAGEDFRAGREFS flag. When SKBFLMANAGEDFRAGREFS is set, the...
kernel: net: atlantic: fix fragment overflow handling in RX path
An out-of-bounds write vulnerability was found in the Aquantia Atlantic network driver in the Linux kernel. When receiving packets that span more than MAXSKBFRAGS 17 fragments, the driver writes beyond the skb fragment array bounds in skbaddrxfrag, causing kernel memory corruption and panic...

kernel: inet: inet_defrag: prevent sk release while still in use
In the Linux kernel, the following vulnerability has been resolved: inet: inetdefrag: prevent sk release while still in use iplocalout and other functions can pass skb-sk as function argument. If the skb is a fragment and reassembly happens before such function call returns, the sk must not be...
Kernel: tcp: excessive resource consumption while processing SACK blocks allows remote denial of service
An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP Selective Acknowledgment SACK segments. While processing SACK segments, the Linux kernel's socket buffer SKB data structure becomes fragmented, which leads to increased resource...
