Linux kernel security vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a potential spectre v1 vulnerability in the dma-buf:heaps module...

CVE-2022-48730

In the Linux kernel, the following vulnerability has been resolved: dma-buf: heaps: Fix potential spectre v1 gadget It appears like nr could be a Spectre v1 gadget as it's supplied by a user and used as an array index. Prevent the contents of kernel memory from being leaked to userspace via...

CVE-2021-47305

In the Linux kernel, the following vulnerability has been resolved: dma-buf/syncfile: Don't leak fences on merge failure Each addfence call does a dmafenceget on the relevant fence. In the error path, we weren't calling dmafenceput so all those fences got leaked. Also, in the kreallocarray failur...
