CVE-2022-48723

In the Linux kernel, the following vulnerability has been resolved: spi: uniphier: fix reference count leak in uniphier_spi_probe() The issue happens in several error paths in uniphier_spi_probe(). When either dma_get_slave_caps() or devm_spi_register_master() returns an error code, the function forgets to decrease the refcount of both `dma_rx` and `dma_tx` objects, which may lead to refcount leaks. Fix it by decrementing the reference count of specific objects in those error paths.

Summary		(es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: spi: uniphier: corrige la fuga del recuento de referencias en uniphier_spi_probe() El problema ocurre en varias rutas de error en uniphier_spi_probe(). Cuando dma_get_slave_caps() o devm_spi_register_master() devuelven un código de error, la función se olvida de disminuir el recuento de los objetos `dma_rx` y `dma_tx`, lo que puede provocar fugas de recuento. Corríjalo disminuyendo el recuento de referencias de objetos específicos en esas rutas de error.
