The issue occurs\nwhen the DMA buffer is freed by tegra_adma_terminate_all() before the\nvchan completion tasklet finishes accessing it.\n\nThe race condition follows this sequence:\n\n 1. DMA transfer completes, triggering an interrupt that schedules the\n completion tasklet (tasklet has not executed yet)\n 2. Audio playback stops, calling tegra_adma_terminate_all() which\n frees the DMA buffer memory via kfree()\n 3. The scheduled tasklet finally executes, calling vchan_complete()\n which attempts to access the already-freed memory\n\nSince tasklets can execute at any time after being scheduled, there is\nno guarantee that the buffer will remain valid when vchan_complete()\nruns.\n\nFix this by properly synchronizing the virtual channel completion:\n - Calling vchan_terminate_vdesc() in tegra_adma_stop() to mark the\n descriptors as terminated instead of freeing the descriptor.\n - Add the callback tegra_adma_synchronize() that calls\n vchan_synchronize() which kills any pending tasklets and frees any\n terminated descriptors.\n\nCrash logs:\n[ 337.427523] BUG: KASAN: use-after-free in vchan_complete+0x124/0x3b0\n[ 337.427544] Read of size 8 at addr ffff000132055428 by task swapper/0/0\n\n[ 337.427562] Call trace:\n[ 337.427564] dump_backtrace+0x0/0x320\n[ 337.427571] show_stack+0x20/0x30\n[ 337.427575] dump_stack_lvl+0x68/0x84\n[ 337.427584] print_address_description.constprop.0+0x74/0x2b8\n[ 337.427590] kasan_report+0x1f4/0x210\n[ 337.427598] __asan_load8+0xa0/0xd0\n[ 337.427603] vchan_complete+0x124/0x3b0\n[ 337.427609] tasklet_action_common.constprop.0+0x190/0x1d0\n[ 337.427617] tasklet_action+0x30/0x40\n[ 337.427623] __do_softirq+0x1a0/0x5c4\n[ 337.427628] irq_exit+0x110/0x140\n[ 337.427633] handle_domain_irq+0xa4/0xe0\n[ 337.427640] gic_handle_irq+0x64/0x160\n[ 337.427644] call_on_irq_stack+0x20/0x4c\n[ 337.427649] do_interrupt_handler+0x7c/0x90\n[ 337.427654] el1_interrupt+0x30/0x80\n[ 337.427659] el1h_64_irq_handler+0x18/0x30\n[ 337.427663] el1h_64_irq+0x7c/0x80\n[ 337.427667] cpuidle_enter_state+0xe4/0x540\n[ 337.427674] cpuidle_enter+0x54/0x80\n[ 337.427679] do_idle+0x2e0/0x380\n[ 337.427685] cpu_startup_entry+0x2c/0x70\n[ 337.427690] rest_init+0x114/0x130\n[ 337.427695] arch_call_rest_init+0x18/0x24\n[ 337.427702] start_kernel+0x380/0x3b4\n[ 337.427706] __primary_switched+0xc0/0xc8", "affected": [ { "vendor": "Linux", "product": "Linux", "defaultStatus": "unaffected", "versions": [ { "version": "f46b195799b5cb05338e7c44cb3617eacb56d755", "status": "affected", "versionType": "git", "lessThan": "5f8d1d66a952d0396671e1f21ff8127a4d14fb4e" }, { "version": "f46b195799b5cb05338e7c44cb3617eacb56d755", "status": "affected", "versionType": "git", "lessThan": "76992310f80776b4d1f7f8915f59b92883a3e44c" }, { "version": "f46b195799b5cb05338e7c44cb3617eacb56d755", "status": "affected", "versionType": "git", "lessThan": "ae3eed72de682ddbba507ed2d6b848c21a6b721e" }, { "version": "f46b195799b5cb05338e7c44cb3617eacb56d755", "status": "affected", "versionType": "git", "lessThan": "59cb421b0902fbef2b9512ae8ba198a20f26b41f" }, { "version": "f46b195799b5cb05338e7c44cb3617eacb56d755", "status": "affected", "versionType": "git", "lessThan": "cb2c9c4bb1322cc3c9984ad17db8cdd2663879ca" }, { "version": "f46b195799b5cb05338e7c44cb3617eacb56d755", "status": "affected", "versionType": "git", "lessThan": "be655c3736b3546f39bc8116ffbf2a3b6cac96c4" }, { "version": "f46b195799b5cb05338e7c44cb3617eacb56d755", "status": "affected", "versionType": "git", "lessThan": "2efd07a7c36949e6fa36a69183df24d368bf9e96" } ] }, { "vendor": "Linux", "product": "Linux", "defaultStatus": "affected", "versions": [ { "version": "4.7", "status": "affected" }, { "version": "0", "status": "unaffected", "versionType": "semver", "lessThan": "4.7" }, { "version": "5.10.249", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.10.*" }, { "version": "5.15.199", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.15.*" }, { "version": "6.1.162", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.1.*" }, { "version": "6.6.122", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.6.*" }, { "version": "6.12.67", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.12.*" }, { "version": "6.18.7", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.18.*" }, { "version": "6.19", "status": "unaffected", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*" } ] } ] } } }
