CVE-2024-38553

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A deadlock issue was found in the sungem driver, which is caused by netpoll being in atomic context and disable irq() being called by the .ndo poll controller interface of the sungem driver. The disable irq() function might sleep, leading to a deadlock. The same issue is present in the fec driver, but since it uses NAPI for TX completions, the .ndo poll controller is unnecessary and can be safely removed. The root cause of the issue is related to the netpoll and disable irq() functions.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
