发布于3月6日3月6日 Members Ubuntu: (CVE-2022-48723): linux-intel-iotg-5.15 vulnerability Severity 5 CVSS (AV:L/AC:L/Au:S/C:N/I:N/A:C) Published 06/20/2024 Created 11/21/2024 Added 11/19/2024 Modified 01/28/2025 Description 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.
