But struct dsa_user_priv is fairly small,\nand p->dp means dereferencing 8 bytes starting with offset 16. Most\ndrivers allocate that much private memory anyway, making our access not\nfault, and we discard the bogus data quickly afterwards, so this wasn't\ncaught.\n\nBut the dummy interface is somewhat special in that it calls\nalloc_netdev() with a priv size of 0. So every netdev_priv() dereference\nis invalid, and we get this when we emit a NETDEV_PRECHANGEUPPER event\nwith a VLAN as its new upper:\n\n$ ip link add dummy1 type dummy\n$ ip link add link dummy1 name dummy1.100 type vlan id 100\n[   43.309174] ==================================================================\n[   43.316456] BUG: KASAN: slab-out-of-bounds in dsa_user_prechangeupper+0x30/0xe8\n[   43.323835] Read of size 8 at addr ffff3f86481d2990 by task ip/374\n[   43.330058]\n[   43.342436] Call trace:\n[   43.366542]  dsa_user_prechangeupper+0x30/0xe8\n[   43.371024]  dsa_user_netdevice_event+0xb38/0xee8\n[   43.375768]  notifier_call_chain+0xa4/0x210\n[   43.379985]  raw_notifier_call_chain+0x24/0x38\n[   43.384464]  __netdev_upper_dev_link+0x3ec/0x5d8\n[   43.389120]  netdev_upper_dev_link+0x70/0xa8\n[   43.393424]  register_vlan_dev+0x1bc/0x310\n[   43.397554]  vlan_newlink+0x210/0x248\n[   43.401247]  rtnl_newlink+0x9fc/0xe30\n[   43.404942]  rtnetlink_rcv_msg+0x378/0x580\n\nAvoid the kernel oops by dereferencing after the type check, as customary.\n\ud83d\udccf Published: 2024-02-23T14:46:25.420Z\n\ud83d\udccf Modified: 2025-02-21T13:45:05.411Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/9e9953f5e4d6d11a9dad56fdee307bb923302809\n2. https://git.kernel.org/stable/c/69a1e2d938dbbfcff0e064269adf60ad26dbb102\n3. https://git.kernel.org/stable/c/dbd909c20c11f0d29c0054d41e0d1f668a60e8c8\n4. https://git.kernel.org/stable/c/844f104790bd69c2e4dbb9ee3eba46fde1fcea7b", "creation_timestamp": "2025-02-21T14:18:37.000000Z"}, {"uuid": "e72cfdd2-9855-4824-a6ba-4d6b8cd6ca2c", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2024-26596", "type": "seen", "source": "https://www.cisa.gov/news-events/ics-advisories/icsa-25-162-05", "content": "", "creation_timestamp": "2025-06-12T10:00:00.000000Z"}, {"uuid": "b5828d27-b2a2-403b-8acd-6dde4c8c1c3f", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2024-26593", "type": "seen", "source": "https://www.cisa.gov/news-events/ics-advisories/icsa-25-226-15", "content": "", "creation_timestamp": "2025-08-14T10:00:00.000000Z"}, {"uuid": "e66a834a-5aea-495d-9ac6-ee50262f8d14", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2024-26598", "type": "seen", "source": "https://www.cisa.gov/news-events/ics-advisories/icsa-25-226-15", "content": "", "creation_timestamp": "2025-08-14T10:00:00.000000Z"}, {"uuid": "d48206ed-5dde-4fc4-b0d6-a51e1bacea28", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "c933734a-9be8-4142-889e-26e95c752803", "vulnerability": "CVE-2024-26595", "type": "seen", "source": "https://vulnerability.circl.lu/bundle/816dcc8e-f25a-4895-9b59-1bbd9caeccb8", "content": "", "creation_timestamp": "2025-12-03T14:14:49.267740Z"}, {"uuid": "5ca16acd-ca4a-4216-932d-f97ac7e80131", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2024-26595", "type": "seen", "source": "https://www.cert.ssi.gouv.fr/avis/CERTFR-2026-AVI-0316/", "content": "", "creation_timestamp": "2026-03-19T00:00:00.000000Z"}, {"uuid": "fed15448-d1db-4e6e-ad49-38b4f9d4fc4a", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2024-26596", "type": "seen", "source": "Telegram/JIJ4UMv-y3NoXAazf5eX0dO-qnt7nMluoFtVI51ts5GTRLar", "content": "", "creation_timestamp": "2025-02-21T22:10:23.000000Z"}, {"uuid": "9bf1ac4d-bd3f-4010-a9cd-7ec14709dbd0", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2024-26590", "type": "published-proof-of-concept", "source": "https://t.me/DarkWebInformer_CVEAlerts/12914", "content": "\ud83d\udd17 DarkWebInformer.com - Cyber Threat Intelligence\n\ud83d\udccc CVE ID: CVE-2024-26590\n\ud83d\udd25 CVSS Score: N/A\n\ud83d\udd39 Description: In the Linux kernel, the following vulnerability has been resolved:\n\nerofs: fix inconsistent per-file compression format\n\nEROFS can select compression algorithms on a per-file basis, and each\nper-file compression algorithm needs to be marked in the on-disk\nsuperblock for initialization.\n\nHowever, syzkaller can generate inconsistent crafted images that use\nan unsupported algorithmtype for specific inodes, e.g. use MicroLZMA\nalgorithmtype even it's not set in `sbi->available_compr_algs`.
