-
In the Linux kernel, the following vulnerability has been resolved:
io_uring/zcrx: fix sgtable leak on mapping failures
In an unlikely case when iopopulateareadma() fails, which could only happen on a PAGEPOOL32BITARCHWITH64BITDMA machine, iozcrxmaparea() will have an initialised and not freed table. It was supposed to be cleaned up in the error path, but !is_mapped prevents that.
