However, the driver data is only set at the end of probe, after devm_request_irq(), so an interrupt taken in between causes the handlers to pass a NULL pointer to readl() and crash. Pass the private data directly as the devm_request_irq() argument instead of the device pointer, matching what the handlers expect. The Linux kernel CVE team has assigned CVE-2026-80743 to this issue.

Affected files ============== The file(s) affected by this issue are: sound/soc/xilinx/xlnx_formatter_pcm.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/7d857aec162fb02d10ce326aecc1ac7509c31f43 https://git.kernel.org/stable/c/a85315f2eb06adc5597a7103e1910fc7d0d35ffd https://git.kernel.org/stable/c/721cfeb0b9572084435695ae535411b921d1ea68 https://git.kernel.org/stable/c/b4ef887bee4d3c177adac5d1eab8b2de31b08ac3 https://git.kernel.org/stable/c/0d58a70b6dc7b65772e3ef7c43beb91882cf9ed5 https://git.kernel.org/stable/c/f51a540b14eecb8667bbe450192318271b87631e https://git.kernel.org/stable/c/09e4c486348e176c083f8bee9169ae8f408cf8d1 https://git.kernel.org/stable/c/f12afefb7b01f94d6d66d397f323a9914edbf70e
