If physical blocks are not submitted in\nthe incremental order, there should be separate BIOs to avoid dependency\nissues. However, the current code mis-arranges z_erofs_fill_bio_vec()\nand BIO submission which causes unexpected BIO waits.\n\nSecond, managed folios will be connected to their own pclusters for\nefficient inter-queries. However, this is somewhat hard to implement\neasily if overlapped big pclusters exist. Again, these only appear in\nfuzzed images so let's simply fall back to temporary short-lived pages\nfor correctness.\n\nAdditionally, it justifies that referenced managed folios cannot be\ntruncated for now and reverts part of commit 2080ca1ed3e4 (\"erofs: tidy\nup `struct z_erofs_bvec`\") for simplicity although it shouldn't be any\ndifference.\n\ud83d\udccf Published: 2024-10-21T12:14:06.530Z\n\ud83d\udccf Modified: 2025-01-17T13:26:59.000Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/1bf7e414cac303c9aec1be67872e19be8b64980c\n2. https://git.kernel.org/stable/c/b9b30af0e86ffb485301ecd83b9129c9dfb7ebf8\n3. https://git.kernel.org/stable/c/9cfa199bcbbbba31cbf97b2786f44f4464f3f29a\n4. https://git.kernel.org/stable/c/9e2f9d34dd12e6e5b244ec488bcebd0c2d566c50", "creation_timestamp": "2025-01-17T13:56:47.000000Z"} 2025-01-17T13:56:47+00:00 https://vulnerability.circl.lu/sighting/fd032f58-4a45-4353-a2ce-8d43ac51a71e/export 2026-05-10T15:50:19.712250+00:00 Joseph Lee http://cve.circl.lu/user/syspect {"uuid": "fd032f58-4a45-4353-a2ce-8d43ac51a71e", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2024-47736", "type": "seen", "source": "https://www.cert.ssi.gouv.fr/avis/CERTFR-2026-AVI-0316/", "content": "", "creation_timestamp": "2026-03-19T00:00:00.000000Z"} 2026-03-19T00:00:00+00:00 https://vulnerability.circl.lu/sighting/3d5131d2-9dc7-40e9-b5ac-572d91d12b88/export 2026-05-10T15:50:19.708255+00:00 Joseph Lee http://cve.circl.lu/user/syspect {"uuid": "3d5131d2-9dc7-40e9-b5ac-572d91d12b88", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2024-47736", "type": "seen", "source": "https://www.hkcert.org/security-bulletin/debian-linux-kernel-multiple-vulnerabilities_20260506", "content": "", "creation_timestamp": "2026-05-05T20:00:00.000000Z"} 2026-05-05T20:00:00+00:00
