In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to clear dirty inode in f2fs_evict_inode() As Yanming reported in bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=215904 The kernel message is shown below: kernel BUG at fs/f2fs/inode.c:825! Call Trace: evict+0x282/0x4e0 __dentry_kill+0x2b2/0x4d0 shrink_dentry_list+0x17c/0x4f0 shrink_dcache_parent+0x143/0x1e0 do_one_tree+0x9/0x30 shrink_dcache_for_umount+0x51/0x120 generic_shutdown_super+0x5c/0x3a0 kill_block_super+0x90/0xd0 kill_f2fs_super+0x225/0x310 deactivate_locked_super+0x78/0xc0 cleanup_mnt+0x2b7/0x480 task_work_run+0xc8/0x150 exit_to_user_mode_prepare+0x14a/0x150 syscall_exit_to_user_mode+0x1d/0x40 do_syscall_64+0x48/0x90 The root cause is: inode node and dnode node share the same nid, so during f2fs_evict_inode(), dnode node truncation will invalidate its NAT entry, so when truncating inode node, it fails due to invalid NAT entry, result in inode is still marked as dirty, fix this issue by clearing dirty for inode and setting SBI_NEED_FSCK flag in filesystem. output from dump.f2fs: [print_node_info: 354] Node ID [0xf:15] is inode i_nid[0] [0x f : 15]
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 5.5, requiring local system access to exploit with relatively low complexity without requiring user interaction requiring only low-level privileges . The vulnerability impacts and availability (service disruption) for affected systems. Impacting 1 product from linux organizations running these solutions should prioritize assessment and patching.
Reported in 2025, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For linux's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
