SUSE CVE-2021-47057

In the Linux kernel, the following vulnerability has been resolved: crypto: sun8i-ss - Fix memory leak of object d when dmaiv fails to map In the case where the dmaiv mapping fails, the return error path leaks the memory allocated to object d. Fix this by adding a new error return label and jumpi...

SUSE CVE-2021-47064

In the Linux kernel, the following vulnerability has been resolved: mt76: fix potential DMA mapping leak With buf uninitialized in mt76dmatxqueueskbraw, its field skipunmap could potentially inherit a non-zero value from stack garbage. If this happens, it will cause DMA mappings for MCU command...

Linux kernel security vulnerabilities

The Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. A security vulnerability exists in the Linux kernel that stems from allowing a call to dmaentryalloccheckleak under freeentrieslock...

CVE-2021-47064

CVE-2021-47064 concerns the Linux kernel mt76 wireless driver. The issue arises in the mt76_dma_tx_queue_skb_raw path where buf can be uninitialized, causing the field skip_unmap to inherit a non-zero value from stack garbage. As a result, DMA mappings for MCU command frames may not be unmapped a...
