{"id":"DEBIAN-CVE-2023-54124","details":"In the Linux kernel, the following vulnerability has been resolved:  f2fs: fix to drop all dirty pages during umount() if cp_error is set  xfstest generic/361 reports a bug as below:  f2fs_bug_on(sbi, sbi-\u003efsync_node_num);  kernel BUG at fs/f2fs/super.c:1627! RIP: 0010:f2fs_put_super+0x3a8/0x3b0 Call Trace:  generic_shutdown_super+0x8c/0x1b0  kill_block_super+0x2b/0x60  kill_f2fs_super+0x87/0x110  deactivate_locked_super+0x39/0x80  deactivate_super+0x46/0x50  cleanup_mnt+0x109/0x170  __cleanup_mnt+0x16/0x20  task_work_run+0x65/0xa0  exit_to_user_mode_prepare+0x175/0x190  syscall_exit_to_user_mode+0x25/0x50  do_syscall_64+0x4c/0x90  entry_SYSCALL_64_after_hwframe+0x72/0xdc  During umount(), if cp_error is set, f2fs_wait_on_all_pages() should not stop waiting all F2FS_WB_CP_DATA pages to be writebacked, otherwise, fsync_node_num can be non-zero after f2fs_wait_on_all_pages() causing this bug.  In this case, to avoid deadloop in f2fs_wait_on_all_pages(), it needs to drop all dirty pages rather than redirtying them.","modified":"2026-09-15T09:02:56.714132734Z","published":"2025-12-24T13:16:14.367Z","upstream":["CVE-2023-54124"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-54124"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.37-1"}]}],"versions":["6.1.27-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54124.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.3.7-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54124.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.3.7-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54124.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
