CVE-2026-46323

A flaw was found in the Linux kernel's Generic Receive Offload GRO networking subsystem. This vulnerability occurs when skbgroreceive attempts to merge zerocopy socket buffers skbs without properly managing page reference counts, specifically when the SKBFLMANAGEDFRAGREFS flag is set. An attacker...

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...

CVE-2026-46330

The CVE describes a Linux kernel design flaw in the net/smc TCP ULP support that was reverted and resolved. The issue arose from attempting to convert an active TCP socket into an SMC socket by in-place modifications to the underlying file structures (struct file, dentry, inode), which violates V...
