A fix is available and has been applied in the Linux kernel. Users should update to the fixed versions identified by the commits b022da127bd9d2217e8f285e643caf5aff6f7f14 and 4e53116437e919c4b9a9d95fb73ae14fe0cfc8f9. No additional mitigation is required beyond applying the official patch.
Description
CVE-2026-43095 addresses a vulnerability in the Linux kernel's ASoC SDCA component related to improper IRQ cleanup. The issue arises because IRQs requested via devm_request_threaded_irq() during component probe can persist after the sound card is torn down, leading to potential crashes due to dangling references. The fix involves removing the use of devm for IRQ requests and implementing manual cleanup to prevent these errors.
