SUSE CVE-2026-53216

In the Linux kernel, the following vulnerability has been resolved: net: mvpp2: limit XDP frame size to the RX buffer mvpp2 has short and long BM pools, and short pool buffers can be smaller than PAGESIZE. The XDP path nevertheless initializes every xdpbuff with PAGESIZE as frame size. XDP helper...

CVE-2026-53215

A flaw was found in the Linux kernel's mvpp2 network driver. This vulnerability occurs due to incorrect handling of receive RX buffers, where a buffer is returned to the hardware Buffer Manager BM pool after it has been passed to the eXpress Data Path XDP or attached to a socket buffer skb. This...

CVE-2026-53229

A flaw was found in the Linux kernel's mlx5e driver. When an XDP eXpress Data Path transmission fails, the driver does not properly unmap DMA Direct Memory Access addresses or free allocated XDP frames. This oversight can lead to a continuous leak of DMA resources and XDP frames, potentially...

UBUNTU-CVE-2026-53215

In the Linux kernel, the following vulnerability has been resolved: net: mvpp2: refill RX buffers before XDP or skb use The RX error path returns the current descriptor buffer to the hardware BM pool. That is only valid while the driver still owns the buffer. mvpp2rxrefill can fail after the...

CVE-2026-53229

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: xsk: Fix DMA and xdpframe leak on XDPTX xmit failure In the XSK branch of mlx5exmitxdpbuff, when sq-xmitxdpframe returns false e.g. XDPSQ is full, the function returns without unmapping the DMA address or freeing the...

CVE-2026-53216

The CVE-2026-53216 issue affects the Linux kernel mvpp2 XDP path. Short pool buffers can be smaller than PAGE_SIZE, yet XDP initially sets every xdp_buff frame size to PAGE_SIZE. The XDP helpers then use frame_sz to validate tail growth, which, with an oversized frame, can allow bpf_xdp_adjust_ta...
