Because the interrupt may occur immediately after devm_request_irq(), the handler may execute before init_completion(). This may result in calling complete() on an uninitialized completion, causing undefined behavior. This has been observed with KASAN. Fix this by initializing the completion before registering the IRQ. The Linux kernel CVE team has assigned CVE-2026-72133 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/spi/spi-uniphier.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/b9fcf0db433d79648ace74bc2b8b88f91e306304 https://git.kernel.org/stable/c/82a5746c4c9e94f6f816ec7edea6ddc24417c6a5 https://git.kernel.org/stable/c/f4bb0a91f7badd6d15ac8d783a1169d9e1e95c17 https://git.kernel.org/stable/c/49f6705d80b5e6175d8435d9c72b66bd516a8e89 https://git.kernel.org/stable/c/8b5798ce0007874c14611b8ee4ce6c749855260e https://git.kernel.org/stable/c/d44b828eb551bd59ba9f22457825cc3db3a39fc1 https://git.kernel.org/stable/c/077a7bc1c32d3da9670c5e282ea3e5ac8a94be59 https://git.kernel.org/stable/c/f3ad1c87d8201e54b66bd6072442f0b5d5a308ee
