Overview
CVE-2026-97412 is a known-severity vulnerability. It was published on September 24, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
pds_core: quiesce DMA before freeing resources
pdsc_teardown() frees DMA buffers but does not disable bus mastering,
leaving the device able to perform DMA after the buffers are freed.
This can lead to use-after-free if the device writes to freed memory.
Add pci_clear_master() to pdsc_teardown() to disable bus mastering
before freeing resources, ensuring all DMA is quiesced.
Add pci_set_master() to pdsc_setup() to re-enable bus mastering,
which is needed for the firmware recovery path since pdsc_teardown()
now disables it.
