https://notcve.org/view.php?id=CVE-2024-36029
In the Linux kernel, the following vulnerability has been resolved: mmc: sdhci-msm: pervent access to suspended controller Generic sdhci code registers LED device and uses host->runtime_suspended flag to protect access to it. The sdhci-msm driver doesn't set this flag, which causes a crash when LED is accessed while controller is runtime suspended. Fix this by setting the flag correctly. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mmc: sdhci-msm: acceso prohibido al controlador suspendido El código sdhci genérico registra el dispositivo LED y utiliza el indicador host->runtime_suspended para proteger el acceso al mismo. El controlador sdhci-msm no establece este indicador, lo que provoca un bloqueo cuando se accede al LED mientras el controlador está suspendido en tiempo de ejecución. • https://git.kernel.org/stable/c/67e6db113c903f2b8af924400b7b43ade4b9ac5c https://git.kernel.org/stable/c/1200481cd6069d16ce20133bcd86f5825e26a045 https://git.kernel.org/stable/c/a957ea5aa3d3518067a1ba32c6127322ad348d20 https://git.kernel.org/stable/c/56b99a52229d7f8cd1f53d899f57aa7eb4b199af https://git.kernel.org/stable/c/f653b04a818c490b045c97834d559911479aa1c5 https://git.kernel.org/stable/c/f8def10f73a516b771051a2f70f2f0446902cb4f •
