{"id":"DEBIAN-CVE-2022-50864","details":"In the Linux kernel, the following vulnerability has been resolved:  nilfs2: fix shift-out-of-bounds due to too large exponent of block size  If field s_log_block_size of superblock data is corrupted and too large, init_nilfs() and load_nilfs() still can trigger a shift-out-of-bounds warning followed by a kernel panic (if panic_on_warn is set):   shift exponent 38973 is too large for 32-bit type 'int'  Call Trace:   \u003cTASK\u003e   dump_stack_lvl+0xcd/0x134   ubsan_epilogue+0xb/0x50   __ubsan_handle_shift_out_of_bounds.cold.12+0x17b/0x1f5   init_nilfs.cold.11+0x18/0x1d [nilfs2]   nilfs_mount+0x9b5/0x12b0 [nilfs2]   ...  This fixes the issue by adding and using a new helper function for getting block size with sanity check.","modified":"2026-09-01T16:05:36.497365334Z","published":"2025-12-30T13:16:01.207Z","upstream":["CVE-2022-50864"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-50864"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-50864.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-50864.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-50864.json"}}],"schema_version":"1.9.0"}
