CVE-2026-53216 net: mvpp2: limit XDP frame size to the RX buffer

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-2026-53216

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...

CVE-2026-53215 net: mvpp2: refill RX buffers before XDP or skb use

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-2026-53202

The CVE-2026-53202 issue affects the Linux kernel component accel/ivpu in IPC receive handling. It describes a signed integer truncation when data_size from firmware is cast to a signed int, leading to a potential unsigned wraparound with large values (≥ 0x80000000). This could enable oversized m...

CVE-2026-53202

In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Fix signed integer truncation in IPC receive Fix potential buffer overflow where firmware-supplied datasize is cast to signed int before being used in mint. Large unsigned values = 0x80000000 become negative, causing...

CVE-2026-53191

CVE-2026-53191 affects the Linux kernel io_uring/net path. In bundle recv retries (with incremental mode and provided buffer rings IOU_PBUF_RING_INC), a memory handling bug caused IORING_CQE_F_BUF_MORE to be dropped during flag merge, allowing the kernel to leave a stale BUF_MORE in carried flags...

CVE-2026-53183

CVE-2026-53183 affects the Linux kernel MPTCP implementation. The issue allows the TCP subflow receive window to shrink independently of the netns, which can inflate the MPTCP receive window and cause incoming data to exceed the receiver’s rcvbuf, potentially leading to DoS or a system becoming u...
