CVE-2026-46007
Beschrijving NL
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (powerz) Avoid cacheline sharing for DMA buffer
Depending on the architecture the transfer buffer may share a cacheline
with the following mutex. As the buffer may be used for DMA, that is
problematic. Use the high-level DMA helpers to make sure that cacheline sharing can
not happen. Also drop the comment, as the helpers are documentation enough. https://sashiko.dev/#/message/20260408175814.934BFC19421%40smtp.kernel.org
