Ubuntu.comUB:CVE-2022-48723CVE-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.
