Description

dmaengine: qcom-adm: fix wrong sizeof config in slave_config

In the Linux kernel, the following vulnerability has been resolved:

dmaengine: qcom-adm: fix wrong sizeof config in slave_config

Fix broken slave_config function that uncorrectly compare the

peripheral_size with the size of the config pointer instead of the size

of the config struct. This cause the crci value to be ignored and cause

a kernel panic on any slave that use adm driver.

To fix this, compare to the size of the struct and NOT the size of the

pointer.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
