CVE-2022-48723: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: from 5.6, before 5.10.99 (fixed in 5.10.99); from 5.11, before 5.15.22 (fixed in 5.15.22); from 5.16, before 5.16.8 (fixed in 5.16.8); version 5.17 only
