{"id":"DEBIAN-CVE-2022-49217","details":"In the Linux kernel, the following vulnerability has been resolved:  scsi: pm8001: Fix abort all task initialization  In pm80xx_send_abort_all(), the n_elem field of the ccb used is not initialized to 0. This missing initialization sometimes lead to the task completion path seeing the ccb with a non-zero n_elem resulting in the execution of invalid dma_unmap_sg() calls in pm8001_ccb_task_free(), causing a crash such as:  [  197.676341] RIP: 0010:iommu_dma_unmap_sg+0x6d/0x280 [  197.700204] RSP: 0018:ffff889bbcf89c88 EFLAGS: 00010012 [  197.705485] RAX: dffffc0000000000 RBX: 0000000000000000 RCX: ffffffff83d0bda0 [  197.712687] RDX: 0000000000000002 RSI: 0000000000000000 RDI: ffff88810dffc0d0 [  197.719887] RBP: 0000000000000000 R08: 0000000000000000 R09: ffff8881c790098b [  197.727089] R10: ffffed1038f20131 R11: 0000000000000001 R12: 0000000000000000 [  197.734296] R13: ffff88810dffc0d0 R14: 0000000000000010 R15: 0000000000000000 [  197.741493] FS:  0000000000000000(0000) GS:ffff889bbcf80000(0000) knlGS:0000000000000000 [  197.749659] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [  197.755459] CR2: 00007f16c1b42734 CR3: 0000000004814000 CR4: 0000000000350ee0 [  197.762656] Call Trace: [  197.765127]  \u003cIRQ\u003e [  197.767162]  pm8001_ccb_task_free+0x5f1/0x820 [pm80xx] [  197.772364]  ? do_raw_spin_unlock+0x54/0x220 [  197.776680]  pm8001_mpi_task_abort_resp+0x2ce/0x4f0 [pm80xx] [  197.782406]  process_oq+0xe85/0x7890 [pm80xx] [  197.786817]  ? lock_acquire+0x194/0x490 [  197.790697]  ? handle_irq_event+0x10e/0x1b0 [  197.794920]  ? mpi_sata_completion+0x2d70/0x2d70 [pm80xx] [  197.800378]  ? __wake_up_bit+0x100/0x100 [  197.804340]  ? lock_is_held_type+0x98/0x110 [  197.808565]  pm80xx_chip_isr+0x94/0x130 [pm80xx] [  197.813243]  tasklet_action_common.constprop.0+0x24b/0x2f0 [  197.818785]  __do_softirq+0x1b5/0x82d [  197.822485]  ? do_raw_spin_unlock+0x54/0x220 [  197.826799]  __irq_exit_rcu+0x17e/0x1e0 [  197.830678]  irq_exit_rcu+0xa/0x20 [  197.834114]  common_interrupt+0x78/0x90 [  197.840051]  \u003c/IRQ\u003e [  197.844236]  \u003cTASK\u003e [  197.848397]  asm_common_interrupt+0x1e/0x40  Avoid this issue by always initializing the ccb n_elem field to 0 in pm8001_send_abort_all(), pm8001_send_read_log() and pm80xx_send_abort_all().","modified":"2026-09-01T16:05:30.243106790Z","published":"2025-02-26T07:00:58.787Z","upstream":["CVE-2022-49217"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-49217"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.17.3-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49217.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.17.3-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49217.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.17.3-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49217.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"}]}
