kernel: dma-buf/dma-resv: check if the new fence is really later

In the Linux kernel, the following vulnerability has been resolved: dma-buf/dma-resv: check if the new fence is really later Previously when we added a fence to a dmaresv object we always assumed the the newer than all the existing fences. With Jason's work to add an UAPI to explicit export/impor...

The vulnerability of the udmabuf_vm_fault() function in the drivers/dma-buf/udmabuf.c module of Linux kernel allows a attacker to escalate their privileges and execute arbitrary code.

The vulnerability of the udmabufvmfault function in the drivers/dma-buf/udmabuf.c module of Linux operating systems is related to unvalidated array indexing due to incorrect data validation. Exploiting this vulnerability can allow an attacker to enhance their privileges and execute arbitrary code...
