CVE-2024-39492

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mailbox: mtk-cmdq: corrige la advertencia pm_runtime_get_sync() en el apagado de mbox. El valor de retorno de pm_runtime_get_sync() en cmdq_mbox_shutdown() devolverá 1 cuando el estado de tiempo de ejecución pm esté activo, y no queremos recibir el mensaje de advertencia en este caso. Entonces cambiamos el valor de retorno <0 para WARN_ON().

In the Linux kernel, the following vulnerability has been resolved: mailbox: mtk-cmdq: Fix pm_runtime_get_sync() warning in mbox shutdown The return value of pm_runtime_get_sync() in cmdq_mbox_shutdown() will return 1 when pm runtime state is active, and we don't want to get the warning message in this case. So we change the return value < 0 for WARN_ON().

Chenyuan Yang discovered that the CEC driver driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the JFS file system contained an out-of-bounds read vulnerability when printing xattr debug information. A local attacker could use this to cause a denial of service.
