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

Description A flaw exists in the Linux kernel related to the assignment logic of iocb within the f2fs filesystem. A commit introduced an iocb field in a trace event, attempting to assign a pointer and subsequently access its field, leading to a kernel paging request and potential system instability. The issue was identified during trace log printing and resulted in a memory abort. The fix involves copying the necessary variables for printing and addressing similar issues in other parts of the same file.

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