Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contained a flaw where accesses to
dst->dev were not protected using Read-Copy-Update (RCU). This issue was addressed by utilizing RCU in functions such as sk setup caps(), sk dst gso max size(), ip6 dst mtu maybe forward(), ip dst mtu maybe forward(), and ip4 dst hoplimit(). The fix ensures thread safety when accessing the device associated with a destination.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
