{"id":"DEBIAN-CVE-2026-53229","details":"In the Linux kernel, the following vulnerability has been resolved:  net/mlx5e: xsk: Fix DMA and xdp_frame leak on XDP_TX xmit failure  In the XSK branch of mlx5e_xmit_xdp_buff(), when sq-\u003exmit_xdp_frame() returns false (e.g. XDPSQ is full), the function returns without unmapping the DMA address or freeing the xdp_frame allocated by xdp_convert_zc_to_xdp_frame(). The xdpi_fifo push only happens on success, so the completion path cannot recover these entries.  With CONFIG_DMA_API_DEBUG=y, the leak surfaces on driver unbind:    DMA-API: pci 0000:08:00.0: device driver has pending DMA   allocations while released from device [count=1116]   One of leaked entries details: [device address=0x000000010ffd7028]   [size=1534 bytes] [mapped with DMA_TO_DEVICE] [mapped as phy]   WARNING: kernel/dma/debug.c:881 at dma_debug_device_change+0x127/0x180   ...
