Descriptions
In the Linux kernel, the following vulnerability has been resolved: dma: fix call order in dmam_free_coherent dmam_free_coherent() frees a DMA allocation, which makes the
freed vaddr available for reuse, then calls devres_destroy()
to remove and free the data structure used to track the DMA
allocation. Between the two calls, it is possible for a
concurrent task to make an allocation with the same vaddr
and add it to the devres list. If this happens, there will be two entries in the devres list
with the same vaddr and devres_destroy() can free the wrong
entry, triggering the WARN_ON() in dmam_match. Fix by destroying the devres entry before freeing the DMA
allocation. kokonut //net/encryption http://sponge2/b9145fe6-0f72-4325-ac2f-a84d81075b03

Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux kernel contained an integer overflow vulnerability. A local attacker could use this to cause a denial of service. Zheng Wang discovered a use-after-free in the Renesas Ethernet AVB driver in the Linux kernel during device removal. A privileged attacker could use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
