{"id":"DEBIAN-CVE-2022-49318","details":"In the Linux kernel, the following vulnerability has been resolved:  f2fs: remove WARN_ON in f2fs_is_valid_blkaddr  Syzbot triggers two WARNs in f2fs_is_valid_blkaddr and __is_bitmap_valid. For example, in f2fs_is_valid_blkaddr, if type is DATA_GENERIC_ENHANCE or DATA_GENERIC_ENHANCE_READ, it invokes WARN_ON if blkaddr is not in the right range. The call trace is as follows:   f2fs_get_node_info+0x45f/0x1070  read_node_page+0x577/0x1190  __get_node_page.part.0+0x9e/0x10e0  __get_node_page  f2fs_get_node_page+0x109/0x180  do_read_inode  f2fs_iget+0x2a5/0x58b0  f2fs_fill_super+0x3b39/0x7ca0  Fix these two WARNs by replacing WARN_ON with dump_stack.","modified":"2026-09-01T20:04:54.349753531Z","published":"2025-02-26T07:01:08.660Z","upstream":["CVE-2022-49318"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-49318"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.18.5-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49318.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.18.5-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49318.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.18.5-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49318.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:N/I:N/A:H"}]}
