CVE-2022-48976

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

Description A vulnerability in the Linux kernel has been resolved, related to the netfilter: flowtable offload. The issue arises when flow offload queue work() is called in a workqueue without bh disabled, potentially causing a call trace error due to the use of this cpu add() in preemptible code. The error is fixed by using NF FLOW TABLE STAT INC ATOMIC() instead in flow offload queue work(). This change ensures that the function is safe to use in all cases, even though the FLOW CLS REPLACE branch may not be called in a preemptible path.

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