Echo: linux: security update to 6.12.8-1

medium Tenable Self-Hosted Container Security Plugin ID 461777

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: udmabuf: fix memory leak on last
 export_udmabuf() error path In export_udmabuf(), if dma_buf_fd() fails because the FD table is full, a
 dma_buf owning the udmabuf has already been created; but the error handling in udmabuf_create() will tear
 down the udmabuf without doing anything about the containing dma_buf. This leaves a dma_buf in memory that
 contains a dangling pointer; though that doesn't seem to lead to anything bad except a memory leak. Fix it
 by moving the dma_buf_fd() call out of export_udmabuf() so that we can give it different error handling.
 Note that the shape of this code changed a lot in commit 5e72b2b41a21 ("udmabuf: convert udmabuf driver to
 use folios"); but the memory leak seems to have existed since the introduction of udmabuf.
 (CVE-2024-56712)

Solution

Update the linux library and its related packages to version 6.12.8-1 or later.
