CVE-2026-53229

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak occurs in the XSK branch of the mlx5e xmit xdp buff() function. When the sq->xmit xdp frame() function returns false, such as when the XDPSQ is full, the system fails to unmap the DMA address and does not free the xdp frame allocated by xdp convert zc to xdp frame(). Because the xdpi fifo push only occurs upon success, the completion path is unable to recover these entries, leading to a leak of DMA allocations and xdp frame objects.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
