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 · unedited
In the Linux kernel, the following vulnerability has been resolved: irqchip/imx-irqsteer: Handle runtime power management correctly The power domain is automatically activated from clk_prepare(). However, on certain platforms like i.MX8QM and i.MX8QXP, the power-on handling invokes sleeping functions, which triggers the 'scheduling while atomic' bug in the context switch path during device probing: BUG: scheduling while atomic: kworker/u13:1/48/0x00000002 Call trace: __schedule_bug+0x54/0x6c __schedule+0x7f0/0xa94 schedule+0x5c/0xc4 schedule_preempt_disabled+0x24/0x40 __mutex_lock.constprop.0+0x2c0/0x540 __mutex_lock_slowpath+0x14/0x20 mutex_lock+0x48/0x54 clk_prepare_lock+0x44/0xa0 clk_prepare+0x20/0x44 imx_irqsteer_resume+0x28/0xe0 pm_generic_runtime_resume+0x2c/0x44 __genpd_runtime_resume+0x30/0x80 genpd_runtime_resume+0xc8/0x2c0 __rpm_callback+0x48/0x1d8 rpm_callback+0x6c/0x78 rpm_resume+0x490/0x6b4 __pm_runtime_resume+0x50/0x94 irq_chip_pm_get+0x2c/0xa0 __irq_do_set_handler+0x178/0x24c irq_set_chained_handler_and_data+0x60/0xa4 mxc_gpio_probe+0x160/0x4b0 Cure this by implementing the irq_bus_lock/sync_unlock() interrupt chip callbacks and handle power management in them as they are invoked from non-atomic context.

Vendor patch git.kernel.org →
Recommended fix High confidence

Upgrade Linux kernel to 5.4.282+, 5.10.224+, 5.15.165+, or 6.1.103+ (or latest stable release in your major version branch)

  1. Identify the current running Linux kernel version using 'uname -r'
  2. Determine which major kernel branch you are using (e.g., 5.4.x, 5.10.x, 5.15.x, or 6.1.x)
  3. Plan kernel upgrade to a fixed version: 5.4.282 or newer for 5.4 branch, 5.10.224 or newer for 5.10 branch, 5.15.165 or newer for 5.15 branch, or 6.1.103 or newer for 6.1 branch
  4. Obtain the updated kernel package from your distribution's kernel repository or compile from source at https://kernel.org
  5. Reboot the system into the updated kernel to apply the fix
Caveat Kernel upgrades may require matching firmware, bootloader updates, and could introduce regressions in other drivers; test thoroughly in non-production environment first
