Call Trace:  \u003CTASK>  ext4_block_zero_page_range+0x30c/0x380 [ext4]  ext4_truncate+0x436/0x440 [ext4]  ext4_process_orphan+0x5d/0x110 [ext4]  ext4_orphan_cleanup+0x124/0x4f0 [ext4]  ext4_fill_super+0x262d/0x3110 [ext4]  get_tree_bdev_flags+0x132/0x1d0  vfs_get_tree+0x26/0xd0  vfs_cmd_create+0x59/0xe0  __do_sys_fsconfig+0x4ed/0x6b0  do_syscall_64+0x82/0x170  ...  This occurs when processing a symlink inode from the orphan list. The partial block zeroing code in the truncate path calls ext4_dirty_journalled_data() -> folio_mark_dirty(). The latter calls mapping->a_ops->dirty_folio(), but symlink inodes are not assigned an a_ops vector in ext4, hence the crash.  To avoid this problem, update the ext4_dirty_journalled_data() helper to only mark the folio dirty on regular files (for which a_ops is assigned). This also matches the journaling logic in the ext4_symlink() creation path, where ext4_handle_dirty_metadata() is called directly.",null,[],[],[],[14],{"_key":15},"CVE-2025-38220",[],[],[],"2025-07-04T14:15:30.597Z","2026-04-28T20:29:54.228907Z",{"cisa_kev":22,"cisa_ransomware":22,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[24],{"url":25,"sources":26,"tags":28},"https://security-tracker.debian.org/tracker/CVE-2025-38220",[27],"osv_debian",[29],"Advisory",[],[],[33],{"source":27,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":34,"cvss_v4_0":9},{"baseScore":35,"baseSeverity":9,"vectorString":36,"impactScore":37,"exploitabilityScore":38},5.5,"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H",6,4.6,[40],{"ecosystem":41,"name":42,"vendor":43,"product":42,"cpe_part":9,"purl_type":44,"purl_namespace":43,"purl_name":42,"source":9,"versions":45},"Debian","linux","debian","deb",[46,52],{"version":47,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":50,"version_end_type":51,"fixed_in":9},"lt6_12_35_1",true,"ecosystem","6.12.35-1","excluding",{"version":47,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":50,"version_end_type":51,"fixed_in":9}]
