UBUNTU-CVE-2025-38545: Critical severity ubuntu/linux-hwe-edge vulnerability
In the Linux kernel, the following vulnerability has been resolved: net: ethernet: ti: am65-cpsw-nuss: Fix skb size by accounting for skbsharedinfo While transitioning from netdevallocipalign() to buildskb(), memory for the "skbsharedinfo" member of an "skb" was not allocated. Fix this by allocating "PAGESIZE" as the skb length, accounting for the packet length, headroom and tailroom, thereby including the required memory space for skbsharedinfo.
