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: x86/mce: Set up the polling timer
 before CMCI discovery I hit the following on one of my machines: mce: CPU0 BANK15 CMCI inherited storm
 ------------[ cut here ]------------ ODEBUG: assert_init not available (active state 0) object:
 (____ptrval____) object type: timer_list hint: 0x0 WARNING: lib/debugobjects.c:632 at
 debug_object_assert_init+0x178/0x230, CPU#0: swapper/0/0 CPU: 0 UID: 0 PID: 0 Comm: swapper/0 Not tainted
 7.2.0-rc5 #3 PREEMPTLAZY RIP: 0010:debug_object_assert_init+0x18f/0x230 Call Trace: <TASK> __mod_timer
 mce_timer_kick cmci_discover intel_init_cmci mce_intel_feature_init mcheck_cpu_init identify_cpu
 identify_boot_cpu arch_cpu_finalize_init start_kernel A second splat follows right after, from
 timer_setup() finding that same timer already queued: ODEBUG: init active (active state 0) object:
 (____ptrval____) object type: timer_list hint: stub_timer+0x0/0x10 This is happening because CMCI storm
 detection is trying to modify the timer before latter was properly set up. Set up the timer first.
 __mcheck_cpu_setup_timer() only calls timer_setup(), and depends on neither the generic nor the vendor
 init. [ bp: Massage commit message. ] (CVE-2026-80727)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.448.8 or later.
