CVE-2025-37909

CVE-2025-37909 affects the Linux kernel net: lan743x subsystem. When GSO is enabled and fragments count is zero, skb is mapped to an EXT descriptor, preventing it from being freed and causing a memory leak. The fix maps the skb to the LS descriptor unconditionally, eliminating the memleak. This i...
