CVE-2022-50142 Information

Jun 19, 2025 cve

Description

In the Linux kernel the following vulnerability has been resolved:

intel_th: msu: Fix vmalloced buffers

After commit f5ff79fddf0e (\dma-mapping: remove CONFIG_DMA_REMAP) there’s a chance of DMA buffer getting allocated via vmalloc() which messes up the mmapping code:

RIP: msc_mmap_fault [intel_th_msu] Call Trace: __do_fault do_fault …

Fix this by accounting for vmalloc possibility.
