Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A permission check bug has been identified in the Linux kernel, specifically in the net/nfc/rawsock.c file. The issue arises from the function
rawsock create() calling a privileged function sk alloc(), which requires a namespace-aware check using ns capable() to verify net->user ns. However, the original code incorrectly checks the init user ns using capable(). This bug has been resolved by replacing capable() with ns capable().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
