{"id":"DEBIAN-CVE-2024-38598","details":"In the Linux kernel, the following vulnerability has been resolved:  md: fix resync softlockup when bitmap size is less than array size  Is is reported that for dm-raid10, lvextend + lvchange --syncaction will trigger following softlockup:  kernel:watchdog: BUG: soft lockup - CPU#3 stuck for 26s! [mdX_resync:6976] CPU: 7 PID: 3588 Comm: mdX_resync Kdump: loaded Not tainted 6.9.0-rc4-next-20240419 #1 RIP: 0010:_raw_spin_unlock_irq+0x13/0x30 Call Trace:  \u003cTASK\u003e  md_bitmap_start_sync+0x6b/0xf0  raid10_sync_request+0x25c/0x1b40 [raid10]  md_do_sync+0x64b/0x1020  md_thread+0xa7/0x170  kthread+0xcf/0x100  ret_from_fork+0x30/0x50  ret_from_fork_asm+0x1a/0x30  And the detailed process is as follows:  md_do_sync  j = mddev-\u003eresync_min  while (j \u003c max_sectors)   sectors = raid10_sync_request(mddev, j, &skipped)    if (!md_bitmap_start_sync(..., &sync_blocks))     // md_bitmap_start_sync set sync_blocks to 0     return sync_blocks + sectors_skippe;   // sectors = 0;   j += sectors;   // j never change  Root cause is that commit 301867b1c168 (\"md/raid10: check slab-out-of-bounds in md_bitmap_get_counter\") return early from md_bitmap_get_counter(), without setting returned blocks.  Fix this problem by always set returned blocks from md_bitmap_get_counter\"(), as it used to be.  Noted that this patch just fix the softlockup problem in kernel, the case that bitmap size doesn't match array size still need to be fixed.","modified":"2026-09-15T09:03:14.235835413Z","published":"2024-06-19T14:15:19.813Z","upstream":["CVE-2024-38598"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-38598"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.94-1"}]}],"versions":["6.1.27-1","6.1.37-1","6.1.38-1","6.1.38-2","6.1.38-2~bpo11+1","6.1.38-3","6.1.38-4","6.1.38-4~bpo11+1","6.1.52-1","6.1.55-1","6.1.55-1~bpo11+1","6.1.64-1","6.1.66-1","6.1.67-1","6.1.69-1","6.1.69-1~bpo11+1","6.1.76-1","6.1.76-1~bpo11+1","6.1.82-1","6.1.85-1","6.1.90-1","6.1.90-1~bpo11+1","6.1.94-1~bpo11+1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-38598.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.8.12-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-38598.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.8.12-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-38598.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"}]}
