Echo: linux: security update to 6.1.162-1

medium Tenable Self-Hosted Container Security Plugin ID 465084

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/i915/gem: Zero-initialize the
 eb.vma array in i915_gem_do_execbuffer Initialize the eb.vma array with values of 0 when the eb structure
 is first set up. In particular, this sets the eb->vma[i].vma pointers to NULL, simplifying cleanup and
 getting rid of the bug described below. During the execution of eb_lookup_vmas(), the eb->vma array is
 successively filled up with struct eb_vma objects. This process includes calling eb_add_vma(), which might
 fail; however, even in the event of failure, eb->vma[i].vma is set for the currently processed buffer. If
 eb_add_vma() fails, eb_lookup_vmas() returns with an error, which prompts a call to eb_release_vmas() to
 clean up the mess. Since eb_lookup_vmas() might fail during processing any (possibly not first) buffer,
 eb_release_vmas() checks whether a buffer's vma is NULL to know at what point did the lookup function
 fail. In eb_lookup_vmas(), eb->vma[i].vma is set to NULL if either the helper function eb_lookup_vma() or
 eb_validate_vma() fails. eb->vma[i+1].vma is set to NULL in case i915_gem_object_userptr_submit_init()
 fails; the current one needs to be cleaned up by eb_release_vmas() at this point, so the next one is set.
 If eb_add_vma() fails, neither the current nor the next vma is set to NULL, which is a source of a NULL
 deref bug described in the issue linked in the Closes tag. When entering eb_lookup_vmas(), the vma
 pointers are set to the slab poison value, instead of NULL. This doesn't matter for the actual lookup,
 since it gets overwritten anyway, however the eb_release_vmas() function only recognizes NULL as the
 stopping value, hence the pointers are being set to NULL as they go in case of intermediate failure. This
 patch changes the approach to filling them all with NULL at the start instead, rather than handling that
 manually during failure. (cherry picked from commit 08889b706d4f0b8d2352b7ca29c2d8df4d0787cd)
 (CVE-2025-71130)
