CVE-2026-53247: Linux kernel Ethernet driver can free memory too soon
CVE-2026-53247 · published 3 months ago
Summary
The Ethernet driver in recent Linux kernel releases for Debian and several Canonical kernels can release a piece of memory before it is safe, potentially causing the system to crash or behave unpredictably. This happens when the driver removes network metadata while some network packets still reference it. Install the latest kernel updates from your distribution as soon as they are available to apply the fix.

Original advisory text
CVE-2026-53247 in linux - Patched by Root
In the Linux kernel, the following vulnerability has been resolved: net: ethernet: mtk_eth_soc: Fix use-after-free in metadata dst teardown mtk_free_dev() calls metadata_dst_free() which frees the metadata_dst with kfree() immediately, bypassing the RCU grace period. In the RX path, skb_dst_set_noref() sets a non-refcounted pointer from the skb to the metadata_dst. This function requires RCU read-side protection and the dst must remain valid until all RCU readers complete. Since metadata_dst_free() calls kfree() directly, a use-after-free can occur if any skb still holds a noref pointer to the dst when the driver tears it down. Replace metadata_dst_free() with dst_release() which properly goes through the refcount path: when the refcount drops to zero, it schedules the actual free via call_rcu_hurry(), ensuring all RCU readers have completed before the memory is freed.
