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: ASoC: SDCA: Fix errors in IRQ cleanup IRQs are enabled through sdca_irq_populate() from component probe using devm_request_threaded_irq(), this however means the IRQs can persist if the sound card is torn down. Some of the IRQ handlers store references to the card and the kcontrols which can then fail. Some detail of the crash was explained in [1]. Generally it is not advised to use devm outside of bus probe, so the code is updated to not use devm. The IRQ requests are not moved to bus probe time as it makes passing the snd_soc_component into the IRQs very awkward and would the require a second step once the component is available, so it is simpler to just register the IRQs at this point, even though that necessitates some manual cleanup.

Recommended fix High confidence

Linux Kernel 6.19.14 or later

  1. Identify the current Linux kernel version using `uname -r` or `cat /proc/version`
  2. Download the kernel source or packages for version 6.19.14 or later from https://www.kernel.org/ or your distribution's package repositories
  3. If using a distribution package manager (e.g., apt, yum, dnf), run: `sudo apt-get update && sudo apt-get install linux-image-$(uname -r | cut -d'-' -f1)` or equivalent for your distribution
  4. If building from source, apply commit 4e53116437e919c4b9a9d95fb73ae14fe0cfc8f9 or use kernel 6.19.14+ source code
  5. Reboot the system into the updated kernel: `sudo reboot`
  6. Verify the fix is applied by checking the kernel version and confirming the sdca_irq_populate() function no longer uses devm_request_threaded_irq()
Caveat Kernel upgrades may introduce regressions in other drivers or require rebuild of out-of-tree modules; ensure compatibility with system hardware and software stack before production deployment
