CVE-2023-54188

CVE-2023-54188 affects the Linux kernel’s dmaengine for the Apple-admac path. The root cause is that the memory descriptor named current_tx is removed from the issued list when it becomes the current descriptor, causing it to be omitted from the standard freeing flow and leaking memory. The docum...

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 ...
