CVE-2022-50721

CVE-2022-50721 affects the Linux kernel via the dmaengine: qcom-adm module. The vulnerability stems from the function prep_slave_sg returning an error pointer on error instead of NULL, while consumers (e.g., nandc) expect NULL to indicate failure. This mismatch can lead to a kernel panic later in...

CVE-2023-54020

In CVE-2023-54020, the Linux kernel dmaengine sf-pdma had a memory leak: sf_pdma_prep_dma_memcpy() started allocating a new sf_pdma_desc every call after a multithread patch, but sf_pdma_free_desc() was not freeing the old descriptor. The in_use flag was redundant and the leak could cause memory ...

CVE-2023-53755

CVE-2023-53755 fixes a panic in the Linux kernel dmaengine/ptdma by adding a null descriptor check before pt_cmd_callback is invoked. Root cause: pt_issue_pending() could assume at least one descriptor exists in Submitted or Issued queues, but both queues could be empty, leading to a call with a ...
