CVE-2026-43039

CVE-2026-43039 concerns the Linux kernel icssg-prueth driver. In ZC RX dispatch, emac_dispatch_skb_zc() allocates a new skb via napi_alloc_skb() but fails to copy the received packet data from the XDP buffer, causing uninitialized heap memory to be passed up the stack and potentially leaking kern...

In the Linux kernel, the following vulnerability has been resolved: igb: remove napisynchronize in igbdown When an AFXDP zero-copy application terminates abruptly e.g., kill -9, the XSK buffer pool is destroyed but NAPI polling continues. igbcleanrxirqzc repeatedly returns the full budget,...

CVE-2026-31691

A flaw was found in the Linux kernel's igb network driver. When an AFXDP zero-copy application terminates abruptly, the network driver's NAPI polling mechanism can become stuck. This prevents the igbdown function from completing, leading to the TX queue becoming permanently stalled. This can resu...

CVE-2026-31691

The CVE-2026-31691 vulnerability affects the Linux kernel igb driver. It describes a race where igb_down() calls napi_synchronize() before napi_disable(), causing a hang: napi_synchronize() waits on NAPI_STATE_SCHED that never clears, blocking TX and leaving the TX queue stalled. The fix removes ...
