{"id":"CVE-2022-49217","summary":"scsi: pm8001: Fix abort all task initialization","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: pm8001: Fix abort all task initialization\n\nIn pm80xx_send_abort_all(), the n_elem field of the ccb used is not\ninitialized to 0. This missing initialization sometimes lead to the task\ncompletion path seeing the ccb with a non-zero n_elem resulting in the\nexecution of invalid dma_unmap_sg() calls in pm8001_ccb_task_free(),\ncausing a crash such as:\n\n[  197.676341] RIP: 0010:iommu_dma_unmap_sg+0x6d/0x280\n[  197.700204] RSP: 0018:ffff889bbcf89c88 EFLAGS: 00010012\n[  197.705485] RAX: dffffc0000000000 RBX: 0000000000000000 RCX: ffffffff83d0bda0\n[  197.712687] RDX: 0000000000000002 RSI: 0000000000000000 RDI: ffff88810dffc0d0\n[  197.719887] RBP: 0000000000000000 R08: 0000000000000000 R09: ffff8881c790098b\n[  197.727089] R10: ffffed1038f20131 R11: 0000000000000001 R12: 0000000000000000\n[  197.734296] R13: ffff88810dffc0d0 R14: 0000000000000010 R15: 0000000000000000\n[  197.741493] FS:  0000000000000000(0000) GS:ffff889bbcf80000(0000) knlGS:0000000000000000\n[  197.749659] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[  197.755459] CR2: 00007f16c1b42734 CR3: 0000000004814000 CR4: 0000000000350ee0\n[  197.762656] Call Trace:\n[  197.765127]  \u003cIRQ\u003e\n[  197.767162]  pm8001_ccb_task_free+0x5f1/0x820 [pm80xx]\n[  197.772364]  ? do_raw_spin_unlock+0x54/0x220\n[  197.776680]  pm8001_mpi_task_abort_resp+0x2ce/0x4f0 [pm80xx]\n[  197.782406]  process_oq+0xe85/0x7890 [pm80xx]\n[  197.786817]  ? lock_acquire+0x194/0x490\n[  197.790697]  ? handle_irq_event+0x10e/0x1b0\n[  197.794920]  ? mpi_sata_completion+0x2d70/0x2d70 [pm80xx]\n[  197.800378]  ? __wake_up_bit+0x100/0x100\n[  197.804340]  ? lock_is_held_type+0x98/0x110\n[  197.808565]  pm80xx_chip_isr+0x94/0x130 [pm80xx]\n[  197.813243]  tasklet_action_common.constprop.0+0x24b/0x2f0\n[  197.818785]  __do_softirq+0x1b5/0x82d\n[  197.822485]  ? do_raw_spin_unlock+0x54/0x220\n[  197.826799]  __irq_exit_rcu+0x17e/0x1e0\n[  197.830678]  irq_exit_rcu+0xa/0x20\n[  197.834114]  common_interrupt+0x78/0x90\n[  197.840051]  \u003c/IRQ\u003e\n[  197.844236]  \u003cTASK\u003e\n[  197.848397]  asm_common_interrupt+0x1e/0x40\n\nAvoid this issue by always initializing the ccb n_elem field to 0 in\npm8001_send_abort_all(), pm8001_send_read_log() and\npm80xx_send_abort_all().","modified":"2026-04-02T08:27:24.462562Z","published":"2025-02-26T01:55:51.156Z","related":["SUSE-SU-2025:1027-1","SUSE-SU-2025:1176-1","SUSE-SU-2025:1183-1","SUSE-SU-2025:1194-1","SUSE-SU-2025:1241-1","SUSE-SU-2025:1263-1","SUSE-SU-2025:1293-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49217.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/16cd02e0951b520bef324adb9a35afcc92501caf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1824a21b2cedc5774a5adfa74f5f7b90472d8677"},{"type":"WEB","url":"https://git.kernel.org/stable/c/279f318bd7d6e04e6e0bc7b8cd8e190da8fa37a4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/326d894adf89f3c707b7784becbe241830daaab6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/765674e3b30121782a2b792684554baa48c61f5e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7f12845c8389855dbcc67baa068b6832dc4a396e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9914461db82caee6c519acfbe10a86fe11bcdeca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c8db786858d895ac58342f67767b4999ae6538fa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d6ec4471550cc53e96485a7124c5891e6a38d1c3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49217.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49217"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"c6b9ef5779c3e1edfa9de949d2a51252bc347663"},{"fixed":"9914461db82caee6c519acfbe10a86fe11bcdeca"},{"fixed":"d6ec4471550cc53e96485a7124c5891e6a38d1c3"},{"fixed":"1824a21b2cedc5774a5adfa74f5f7b90472d8677"},{"fixed":"765674e3b30121782a2b792684554baa48c61f5e"},{"fixed":"279f318bd7d6e04e6e0bc7b8cd8e190da8fa37a4"},{"fixed":"c8db786858d895ac58342f67767b4999ae6538fa"},{"fixed":"326d894adf89f3c707b7784becbe241830daaab6"},{"fixed":"16cd02e0951b520bef324adb9a35afcc92501caf"},{"fixed":"7f12845c8389855dbcc67baa068b6832dc4a396e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-49217.json"}}],"schema_version":"1.7.5"}
