Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn the Linux kernel, the following vulnerability has been resolved: sched/core: Prevent rescheduling when interrupts are disabled David reported a warning observed while loop testing kexec jump: Interrupts enabled after irqrouter_resume+0x0/0x50 WARNING: CPU: 0 PID: 560 at drivers/base/syscore.c:103 syscore_resume+0x18a/0x220 kernel_kexec+0xf6/0x180 __do_sys_reboot+0x206/0x250 do_syscall_64+0x95/0x180 The corresponding interrupt flag trace: hardirqs last enabled at (15573): [<ffffffffa8281b8e>] __up_console_sem+0x7e/0x90 hardirqs last disabled at (15580): [<ffffffffa8281b73>] __up_console_sem+0x63/0x90 That means __up_console_sem() was invoked with interrupts enabled. Further instrumentation revealed that in the interrupt disabled section of kexec jump one of the syscore_suspend() callbacks woke up a task, which set the NEED_RESCHED flag. A later callback in the resume path invoked cond_resched() which in turn led to the invocation of the scheduler: __cond_resched+0x21/0x60 down_timeout+0x18/0x60 acpi_os_wait_semaphore+0x4c/0x80 acpi_ut_acquire_mutex+0x3d/0x100 acpi_ns_get_node+0x27/0x60 acpi_ns_evaluate+0x1cb/0x2d0 acpi_rs_set_srs_method_data+0x156/0x190 acpi_pci_link_set+0x11c/0x290 irqrouter_resume+0x54/0x60 syscore_resume+0x6a/0x200 kernel_kexec+0x145/0x1c0 __do_sys_reboot+0xeb/0x240 do_syscall_64+0x95/0x180 This is a long standing problem, which probably got more visible with the recent printk changes. Something does a task wakeup and the scheduler sets the NEED_RESCHED flag. cond_resched() sees it set and invokes schedule() from a completely bogus context. The scheduler enables interrupts after context switching, which causes the above warning at the end. Quite some of the code paths in syscore_suspend()/resume() can result in triggering a wakeup with the exactly same consequences. They might not have done so yet, but as they share a lot of code with normal operations it's just a question of time. The problem only affects the PREEMPT_NONE and PREEMPT_VOLUNTARY scheduling models. Full preemption is not affected as cond_resched() is disabled and the preemption check preemptible() takes the interrupt disabled flag into account. Cure the problem by adding a corresponding check into cond_resched().

Recommended fix
High confidence
Upgrade to Linux kernel >= 5.4.291 (5.4.x), >= 5.10.235 (5.10.x), >= 5.15.179 (5.15.x), or >= 6.1.130 (6.1.x) depending on your current branch
- Identify the currently running Linux kernel version using `uname -r`
- Determine which kernel branch you're using (e.g., 5.4.x, 5.10.x, 5.15.x, 6.1.x)
- Upgrade to a kernel version that includes the fix: for 5.4.x series upgrade to >= 5.4.291, for 5.10.x upgrade to >= 5.10.235, for 5.15.x upgrade to >= 5.15.179, or for 6.1.x upgrade to >= 6.1.130
- Apply the appropriate kernel upgrade via your distribution's package manager (e.g., `apt-get dist-upgrade`, `yum update`, or similar)
- Reboot the system to load the fixed kernel
- Verify the new kernel version is running with `uname -r`
Caveat Kernel upgrades may require reboot and could have compatibility implications with custom kernel modules or specific hardware drivers; test in staging first
