Astra Linux – vulnerability in linux-6.1, linux-5.10, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: dma-buf: insert memory barrier before updating numfences smpstoremb inserts a memory barrier after performing the store operation. This differs from what the comment originally intended; thus, a null pointer dereference may occur...

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 Linux kernel that stems from dma-buf not inserting a memory barrier before updating numfences, which could result in a null pointer dereferen...

kernel: dma-buf/dma-resv: Stop leaking on krealloc() failure

In the Linux kernel, the following vulnerability has been resolved: dma-buf/dma-resv: Stop leaking on krealloc failure Currently dmaresvgetfences will leak the previously allocated array if the fence iteration got restarted and the kreallocarray fails. Free the old array by hand, and make sure we...
