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: mm, slub: avoid zeroing kmalloc
redzone Since commit 946fa0dbf2d8 ("mm/slub: extend redzone check to extra allocated kmalloc space than
requested"), setting orig_size treats the wasted space (object_size - orig_size) as a redzone. However
with init_on_free=1 we clear the full object->size, including the redzone. Additionally we clear the
object metadata, including the stored orig_size, making it zero, which makes check_object() treat the
whole object as a redzone. These issues lead to the following BUG report with "slub_debug=FUZ
init_on_free=1": [ 0.000000] =============================================================================

orig_size to clear the used area. And restore the value of orig_size after clear the remaining area. When
CONFIG_SLUB_DEBUG not defined, (get_orig_size()' directly returns s->object_size. So when using memset to
init the area, the size can simply be orig_size, as orig_size returns object_size when CONFIG_SLUB_DEBUG
not enabled. And orig_size can never be bigger than object_size. (CVE-2024-49885)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 19165.0.0 or later.
