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: ima: verify the previous kernel's IMA
buffer lies in addressable RAM Patch series "Address page fault in ima_restore_measurement_list()", v3.
When the second-stage kernel is booted via kexec with a limiting command line such as "mem=<size>" we
observe a pafe fault that happens. BUG: unable to handle page fault for address: ffff97793ff47000 RIP:
ima_restore_measurement_list+0xdc/0x45a #PF: error_code(0x0000) not-present page This happens on x86_64
only, as this is already fixed in aarch64 in commit: cbf9c4b9617b ("of: check previous kernel's ima-kexec-
buffer against memory bounds") This patch (of 3): When the second-stage kernel is booted with a limiting
command line (e.g. "mem=<size>"), the IMA measurement buffer handed over from the previous kernel may fall
outside the addressable RAM of the new kernel. Accessing such a buffer can fault during early restore.
Introduce a small generic helper, ima_validate_range(), which verifies that a physical [start, end] range
for the previous-kernel IMA buffer lies within addressable memory: - On x86, use pfn_range_is_mapped(). -
On OF based architectures, use page_is_ram(). (CVE-2026-43129)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.613.77 or later.
