CVE-2022-49905

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

Description A possible leaked pernet namespace in smc init() has been resolved. The issue occurs when register pernet subsys(&smc net stat ops) is called without error handling. If it fails, the registration of &smc net ops is not reverted, and if smc nl init() fails, &smc net stat ops itself is not reverted. This leaves wild operations in the subsystem's linked list, triggering a page fault when another module tries to call register pernet operations(). The error is characterized by an inability to handle a page fault for a specific address, followed by a call trace that includes register pernet subsys and ebtables init.

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