CVE-2021-47195

CVE-2021-47195 relates to the Linux kernel SPI subsystem. The issue is a use-after-free caused by unlocking a per-controller mutex (add_lock) after the controller has already been freed during spi_unregister_controller(ctlr) and subsequent put_device flow. The fix moves put_device() after the mut...

CVE-2024-26806

A vulnerability was found in the spi: cadence-qspi driver in the Linux kernel, where improper system-wide suspend helper calls were made in the runtime Power Management PM hooks. This issue could lead to unintended behavior during system suspend/resume cycles. Mitigation Mitigation for this issue...

CVE-2024-26807

A vulnerability was found in the Cadence Quad SPI cadence-qspi driver in the Linux kernel. Improper pointer reference handling in the runtime Power Management PM hooks could lead to system instability or potential security risks. Mitigation Mitigation for this issue is either not available or the...

CVE-2024-26807

CVE-2024-26807 affects the Linux kernel via the cadence-quadspi driver path: runtime_suspend() and runtime_resume() incorrectly use dev_get_drvdata to retrieve a struct that is not a valid spi_controller pointer, causing memory corruption during PM runtime if probe enables PM runtime. Local impac...
