"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nPCI: endpoint: pci-epf-test: Add NULL check for DMA channels before release\n\nThe fields dma_chan_tx and dma_chan_rx of the struct pci_epf_test can be\nNULL even after EPF initialization. Then it is prudent to check that\nthey have non-NULL values before releasing the channels. Add the checks\nin pci_epf_test_clean_dma_chan().\n\nWithout the checks, NULL pointer dereferences happen and they can lead\nto a kernel panic in some cases:\n\n Unable to handle kernel NULL pointer dereference at virtual address 0000000000000050\n Call trace:\n dma_release_channel+0x2c/0x120 (P)\n pci_epf_test_epc_deinit+0x94/0xc0 [pci_epf_test]\n pci_epc_deinit_notify+0x74/0xc0\n tegra_pcie_ep_pex_rst_irq+0x250/0x5d8\n irq_thread_fn+0x34/0xb8\n irq_thread+0x18c/0x2e8\n kthread+0x14c/0x210\n ret_from_fork+0x10/0x20\n\n[mani: trimmed the stack trace]"
