Echo: linux: security update to 6.12.48-1

medium Tenable Cloud Security Plugin ID 463188

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: drm/amd/display: fix a Null pointer
dereference vulnerability [Why] A null pointer dereference vulnerability exists in the AMD display
driver's (DC module) cleanup function dc_destruct(). When display control context (dc->ctx) construction
fails (due to memory allocation failure), this pointer remains NULL. During subsequent error handling when
dc_destruct() is called, there's no NULL check before dereferencing the perf_trace member
(dc->ctx->perf_trace), causing a kernel null pointer dereference crash. [How] Check if dc->ctx is non-NULL
before dereferencing. (Updated commit text and removed unnecessary error message) (cherry picked from
commit 9dd8e2ba268c636c240a918e0a31e6feaee19404) (CVE-2025-39705)

Solution

Update the linux library and its related packages to version 6.12.48-1 or later.
