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/gem: Acquire references on GEM
 handles for framebuffers A GEM handle can be released while the GEM buffer object is attached to a DRM
 framebuffer. This leads to the release of the dma-buf backing the buffer object, if any. [1] Trying to use
 the framebuffer in further mode-setting operations leads to a segmentation fault. Most easily happens with
 driver that use shadow planes for vmap-ing the dma-buf during a page flip. An example is shown below. [

 157.346424] ---[ end trace 0000000000000000 ]--- Acquiring GEM handles for the framebuffer's GEM buffer
 objects prevents this from happening. The framebuffer's cleanup later puts the handle references. Commit
 1a148af06000 ("drm/gem-shmem: Use dma_buf from GEM object instance") triggers the segmentation fault
 easily by using the dma-buf field more widely. The underlying issue with reference counting has been
 present before. v2: - acquire the handle instead of the BO (Christian) - fix comment style (Christian) -
 drop the Fixes tag (Christian) - rename err_ gotos - add missing Link tag (CVE-2025-38449)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.339.70 or later.
