{"id":"DEBIAN-CVE-2025-38300","details":"In the Linux kernel, the following vulnerability has been resolved:  crypto: sun8i-ce-cipher - fix error handling in sun8i_ce_cipher_prepare()  Fix two DMA cleanup issues on the error path in sun8i_ce_cipher_prepare():  1] If dma_map_sg() fails for areq-\u003edst, the device driver would try to free    DMA memory it has not allocated in the first place.
