Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
io_uring/zcrx: fix sgtable leak on mapping failures<br />
<br />
In an unlikely case when io_populate_area_dma() fails, which could only<br />
happen on a PAGE_POOL_32BIT_ARCH_WITH_64BIT_DMA machine,<br />
io_zcrx_map_area() will have an initialised and not freed table. It was<br />
supposed to be cleaned up in the error path, but !is_mapped prevents<br />
that.
