CVE-2021-47374
CVE-2021-47374 concerns the Linux kernel DMA debugging code (kernel/dma/debug.c). The issue arises when drivers using the DMA API emit an error condition frequently, causing a flood of printk messages that can drive CPU usage to 100%. The documented fix switches handling from simple rate limiting...
CVE-2021-47374
In the Linux kernel, the following vulnerability has been resolved: dma-debug: prevent an error message from causing runtime problems For some drivers, that use the DMA API. This error message can be reached several millions of times per second, causing spam to the kernel's printk buffer and...
CVE-2021-47305 dma-buf/sync_file: Don't leak fences on merge failure
In the Linux kernel, the following vulnerability has been resolved: dma-buf/syncfile: Don't leak fences on merge failure Each addfence call does a dmafenceget on the relevant fence. In the error path, we weren't calling dmafenceput so all those fences got leaked. Also, in the kreallocarray failur...

CVE-2021-47224 net: ll_temac: Make sure to free skb when it is completely used
In the Linux kernel, the following vulnerability has been resolved: net: lltemac: Make sure to free skb when it is completely used With the skb pointer piggy-backed on the TX BD, we have a simple and efficient way to free the skb buffer when the frame has been transmitted. But in order to avoid...
CVE-2021-47224
CVE-2021-47224 concerns the Linux kernel ll_temac driver. A use-after-free can occur on the DMA side if the skb is freed while fragments are still in use because the skb pointer was piggy-backed on the first TX buffer descriptor (BD). The resolved description states the fix was to ensure the skb ...
