CVE ID : CVE-2025-40172<\/p>\n
Published : Nov. 12, 2025, 11:15 a.m. | 16\u00a0minutes ago<\/p>\n
Description : In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
accel\/qaic: Treat remaining == 0 as error in find_and_map_user_pages()<\/p>\n
Currently, if find_and_map_user_pages() takes a DMA xfer request from the
\nuser with a length field set to 0, or in a rare case, the host receives
\nQAIC_TRANS_DMA_XFER_CONT from the device where resources->xferred_dma_size
\nis equal to the requested transaction size, the function will return 0
\nbefore allocating an sgt or setting the fields of the dma_xfer struct.
\nIn that case, encode_addr_size_pairs() will try to access the sgt which
\nwill lead to a general protection fault.<\/p>\n
Return an EINVAL in case the user provides a zero-sized ALP, or the device
\nrequests continuation after all of the bytes have been transferred.<\/p>\n
Severity: 0.0 | NA<\/p>\n
