{"id":"DEBIAN-CVE-2023-54060","details":"In the Linux kernel, the following vulnerability has been resolved:  iommufd: Set end correctly when doing batch carry  Even though the test suite covers this it somehow became obscured that this wasn't working.  The test iommufd_ioas.mock_domain.access_domain_destory would blow up rarely.  end should be set to 1 because this just pushed an item, the carry, to the pfns list.  Sometimes the test would blow up with:    BUG: kernel NULL pointer dereference, address: 0000000000000000   #PF: supervisor read access in kernel mode   #PF: error_code(0x0000) - not-present page   PGD 0 P4D 0   Oops: 0000 [#1] SMP   CPU: 5 PID: 584 Comm: iommufd Not tainted 6.5.0-rc1-dirty #1236   Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014   RIP: 0010:batch_unpin+0xa2/0x100 [iommufd]   Code: 17 48 81 fe ff ff 07 00 77 70 48 8b 15 b7 be 97 e2 48 85 d2 74 14 48 8b 14 fa 48 85 d2 74 0b 40 0f b6 f6 48 c1 e6 04 48 01 f2 \u003c48\u003e 8b 3a 48 c1 e0 06 89 ca 48 89 de 48 83 e7 f0 48 01 c7 e8 96 dc   RSP: 0018:ffffc90001677a58 EFLAGS: 00010246   RAX: 00007f7e2646f000 RBX: 0000000000000000 RCX: 0000000000000001   RDX: 0000000000000000 RSI: 00000000fefc4c8d RDI: 0000000000fefc4c   RBP: ffffc90001677a80 R08: 0000000000000048 R09: 0000000000000200   R10: 0000000000030b98 R11: ffffffff81f3bb40 R12: 0000000000000001   R13: ffff888101f75800 R14: ffffc90001677ad0 R15: 00000000000001fe   FS:  00007f9323679740(0000) GS:ffff8881ba540000(0000) knlGS:0000000000000000   CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033   CR2: 0000000000000000 CR3: 0000000105ede003 CR4: 00000000003706a0   DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000   DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400   Call Trace:    \u003cTASK\u003e    ? show_regs+0x5c/0x70    ? __die+0x1f/0x60    ? page_fault_oops+0x15d/0x440    ? lock_release+0xbc/0x240    ? exc_page_fault+0x4a4/0x970    ? asm_exc_page_fault+0x27/0x30    ? batch_unpin+0xa2/0x100 [iommufd]    ? batch_unpin+0xba/0x100 [iommufd]    __iopt_area_unfill_domain+0x198/0x430 [iommufd]    ? __mutex_lock+0x8c/0xb80    ? __mutex_lock+0x6aa/0xb80    ? xa_erase+0x28/0x30    ? iopt_table_remove_domain+0x162/0x320 [iommufd]    ? lock_release+0xbc/0x240    iopt_area_unfill_domain+0xd/0x10 [iommufd]    iopt_table_remove_domain+0x195/0x320 [iommufd]    iommufd_hw_pagetable_destroy+0xb3/0x110 [iommufd]    iommufd_object_destroy_user+0x8e/0xf0 [iommufd]    iommufd_device_detach+0xc5/0x140 [iommufd]    iommufd_selftest_destroy+0x1f/0x70 [iommufd]    iommufd_object_destroy_user+0x8e/0xf0 [iommufd]    iommufd_destroy+0x3a/0x50 [iommufd]    iommufd_fops_ioctl+0xfb/0x170 [iommufd]    __x64_sys_ioctl+0x40d/0x9a0    do_syscall_64+0x3c/0x80    entry_SYSCALL_64_after_hwframe+0x46/0xb0","modified":"2026-09-15T09:02:52.665153869Z","published":"2025-12-24T13:16:07.790Z","upstream":["CVE-2023-54060"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-54060"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.4.11-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54060.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.4.11-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54060.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
