Descriptions

In all Qualcomm products with Android releases from CAF using the Linux kernel, during DMA allocation, due to wrong data type of size, allocation size gets truncated which makes allocation succeed when it should fail.

En todos los productos Qualcomm con distribuciones Android desde CAF empleando el kernel Linux, durante la asignación de DMA, el tamaño de asignación se trunca, lo que permite que la asignación sea un éxito cuando debería fallar. Esto se debe a un tipo de tamaño de datos erróneo.

A flaw was found where the kernel truncated the value used to indicate the size of a buffer which it would later become zero using an untruncated value. This can corrupt memory outside of the original allocation.

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include buffer overflow, bypass, denial of service, and use-after-free vulnerabilities.
