The freeze side will grab that rwsem for writing,\nexcluding any new writers from happening and waiting for existing writes\nto finish. But io_uring unconditionally uses kiocb_start_write(), which\nwill block if someone is currently attempting to freeze the mount point.\nThis causes a deadlock where freeze is waiting for previous writes to\ncomplete, but the previous writes cannot complete, as the task that is\nsupposed to complete them is blocked waiting on starting a new write.\nThis results in the following stuck trace showing that dependency with\nthe write blocked starting a new write:\n\ntask:fio             state:D stack:0     pid:886   tgid:886   ppid:876\nCall trace:\n __switch_to+0x1d8/0x348\n __schedule+0x8e8/0x2248\n schedule+0x110/0x3f0\n percpu_rwsem_wait+0x1e8/0x3f8\n __percpu_down_read+0xe8/0x500\n io_write+0xbb8/0xff8\n io_issue_sqe+0x10c/0x1020\n io_submit_sqes+0x614/0x2110\n __arm64_sys_io_uring_enter+0x524/0x1038\n invoke_syscall+0x74/0x268\n el0_svc_common.constprop.0+0x160/0x238\n do_el0_svc+0x44/0x60\n el0_svc+0x44/0xb0\n el0t_64_sync_handler+0x118/0x128\n el0t_64_sync+0x168/0x170\nINFO: task fsfreeze:7364 blocked for more than 15 seconds.\n      Not tainted 6.12.0-rc5-00063-g76aaf945701c #7963\n\nwith the attempting freezer stuck trying to grab the rwsem:\n\ntask:fsfreeze        state:D stack:0     pid:7364  tgid:7364  ppid:995\nCall trace:\n __switch_to+0x1d8/0x348\n __schedule+0x8e8/0x2248\n schedule+0x110/0x3f0\n percpu_down_write+0x2b0/0x680\n freeze_super+0x248/0x8a8\n do_vfs_ioctl+0x149c/0x1b18\n __arm64_sys_ioctl+0xd0/0x1a0\n invoke_syscall+0x74/0x268\n el0_svc_common.constprop.0+0x160/0x238\n do_el0_svc+0x44/0x60\n el0_svc+0x44/0xb0\n el0t_64_sync_handler+0x118/0x128\n el0t_64_sync+0x168/0x170\n\nFix this by having the io_uring side honor IOCB_NOWAIT, and only attempt a\nblocking grab of the super block rwsem if it isn't set. For normal issue\nwhere IOCB_NOWAIT would always be set, this returns -EAGAIN which will\nhave io_uring core issue a blocking attempt of the write. That will in\nturn also get completions run, ensuring forward progress.\n\nSince freezing requires CAP_SYS_ADMIN in the first place, this isn't\nsomething that can be triggered by a regular user."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["io_uring/rw.c"],"versions":[{"version":"2b188cc1bb857a9d4701ae59aa7768b5124e262e","lessThan":"485d9232112b17f389b29497ff41b97b3189546b","status":"affected","versionType":"git"},{"version":"2b188cc1bb857a9d4701ae59aa7768b5124e262e","lessThan":"4e24041ba86d50aaa4c792ae2c88ed01b3d96243","status":"affected","versionType":"git"},{"version":"2b188cc1bb857a9d4701ae59aa7768b5124e262e","lessThan":"9e8debb8e51354b201db494689198078ec2c1e75","status":"affected","versionType":"git"},{"version":"2b188cc1bb857a9d4701ae59aa7768b5124e262e","lessThan":"003d2996964c03dfd34860500428f4cdf1f5879e","status":"affected","versionType":"git"},{"version":"2b188cc1bb857a9d4701ae59aa7768b5124e262e","lessThan":"26b8c48f369b7591f5679e0b90612f4862a32929","status":"affected","versionType":"git"},{"version":"2b188cc1bb857a9d4701ae59aa7768b5124e262e","lessThan":"1d60d74e852647255bd8e76f5a22dc42531e4389","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["io_uring/rw.c"],"versions":[{"version":"5.1","status":"affected"},{"version":"0","lessThan":"5.1","status":"unaffected","versionType":"semver"},{"version":"5.10.230","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.172","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.116","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.60","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.11.7","lessThanOrEqual":"6.11.*","status":"unaffected","versionType":"semver"},{"version":"6.12","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.1","versionEndExcluding":"5.10.230"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.1","versionEndExcluding":"5.15.172"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.1","versionEndExcluding":"6.1.116"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.1","versionEndExcluding":"6.6.60"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.1","versionEndExcluding":"6.11.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.1","versionEndExcluding":"6.12"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/485d9232112b17f389b29497ff41b97b3189546b"},{"url":"https://git.kernel.org/stable/c/4e24041ba86d50aaa4c792ae2c88ed01b3d96243"},{"url":"https://git.kernel.org/stable/c/9e8debb8e51354b201db494689198078ec2c1e75"},{"url":"https://git.kernel.org/stable/c/003d2996964c03dfd34860500428f4cdf1f5879e"},{"url":"https://git.kernel.org/stable/c/26b8c48f369b7591f5679e0b90612f4862a32929"},{"url":"https://git.kernel.org/stable/c/1d60d74e852647255bd8e76f5a22dc42531e4389"}],"title":"io_uring/rw: fix missing NOWAIT check for O_DIRECT start write","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":4.4,"attackVector":"LOCAL","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"HIGH","confidentialityImpact":"NONE"}},{"other":{"type":"ssvc","content":{"id":"CVE-2024-53052","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2025-10-01T20:13:08.688394Z"}}}],"problemTypes":[{"descriptions":[{"lang":"en","type":"CWE","cweId":"CWE-667","description":"CWE-667 Improper Locking"}]}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-10-01T20:17:18.261Z"}},{"title":"CVE Program Container","references":[{"url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html"},{"url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-03T22:28:47.559Z"}}]}}
