CVE-2022-48637

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

Description The issue is related to a use-after-free error in the bnxt component of the Linux kernel. This occurs when the bnxt tx int() function hands over the ownership of a completed skb to the PTP worker and the skb is used afterwards, potentially leading to a use-after-free condition. The worker may run before the rest of the code and free the skb, causing this issue. There is no information provided about the estimated number of potentially affected devices or real-world incidents where this issue was exploited.

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