Description

In the Linux kernel, the following vulnerability has been resolved: dmaengine: at_hdmac: fix device leak on of_dma_xlate() Make sure to drop the reference taken when looking up the DMA platform device during of_dma_xlate() when releasing channel resources. Note that commit 3832b78b3ec2 ("dmaengine: at_hdmac: add missing put_device() call in at_dma_xlate()") fixed the leak in a couple of error paths but the reference is still leaking on successful allocation.

Affected configurations

• linux linux kernel (>= 3.10.1 < 5.10.249) • linux linux kernel (>= 5.11 < 5.15.199) • linux linux kernel (>= 5.16 < 6.1.162) • linux linux kernel (>= 6.2 < 6.6.122) • linux linux kernel (>= 6.7 < 6.12.67) • linux linux kernel (>= 6.13 < 6.18.7) • linux linux kernel 3.10 • linux linux kernel 6.19
