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: crash: fix crashkernel resource shrink
When crashkernel is configured with a high reservation, shrinking its value below the low crashkernel
reservation causes two issues: 1. Invalid crashkernel resource objects 2. Kernel crash if crashkernel
shrinking is done twice For example, with crashkernel=200M,high, the kernel reserves 200MB of high memory
and some default low memory (say 256MB). The reservation appears as: cat /proc/iomem | grep -i crash
af000000-beffffff : Crash kernel 433000000-43f7fffff : Crash kernel If crashkernel is then shrunk to 50MB
(echo 52428800 > /sys/kernel/kexec_crash_size), /proc/iomem still shows 256MB reserved: af000000-beffffff
: Crash kernel Instead, it should show 50MB: af000000-b21fffff : Crash kernel Further shrinking
crashkernel to 40MB causes a kernel crash with the following trace (x86): BUG: kernel NULL pointer
dereference, address: 0000000000000038 PGD 0 P4D 0 Oops: 0000 [#1] PREEMPT SMP NOPTI <snip...> Call Trace:

__crash_shrink_memory()/kernel/crash_core.c incorrectly updates the crashk_res resource object even when
crashk_low_res should be updated. Fix this by ensuring the correct crashkernel resource object is updated
when shrinking crashkernel memory. (CVE-2025-68198)

Solution

Update the sys-kernel/csql-kernel-6_12 library and its related packages to version 19216.104.89 or later.
