CVE-2021-47311

A vulnerability was found in the Linux kernel's Qualcomm EMAC driver, where the emacremove function can lead to a use-after-free issue when the driver tries to access data after the network device has been freed, causing instability and a crash in the network subsystem. Mitigation Red Hat has...

CVE-2023-52871

In the Linux kernel, the following vulnerability has been resolved: soc: qcom: llcc: Handle a second device without data corruption Usually there is only one llcc device. But if there were a second, even a failed probe call would modify the global drvdata pointer. So check if drvdata is valid...
