Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 5.10.234-syzkaller

Description: A flaw exists in the jffs2 file system within the Linux kernel where the result of jffs2 prealloc raw node refs() was not adequately checked in several places. This could lead to a null pointer dereference during garbage collection or file writing operations, potentially causing system instability or denial of service. The issue was discovered through fuzzing using Syzkaller by the Linux Verification Center.

Recommendations: Linux kernel versions prior to 5.10.234-syzkaller should be updated to version 5.10.234-syzkaller or later.
