quiesce DMA before freeing resources","description":"In the Linux kernel, the following vulnerability has been resolved:\n\npds_core: quiesce DMA before freeing resources\n\npdsc_teardown() frees DMA buffers but does not disable bus mastering,\nleaving the device able to perform DMA after the buffers are freed.\nThis can lead to use-after-free if the device writes to freed memory.\n\nAdd pci_clear_master() to pdsc_teardown() to disable bus mastering\nbefore freeing resources, ensuring all DMA is quiesced.\n\nAdd pci_set_master() to pdsc_setup() to re-enable bus mastering,\nwhich is needed for the firmware recovery path since pdsc_teardown()\nnow disables it.","state":0,"publishedAt":"2026-09-24T16:03:19.355+00:00","modifiedAt":"2026-10-21T12:52:43.054+00:00","affected":[{"ecosystem":"Vendor
