Summary
In the Linux kernel, the following vulnerability has been resolved: media: amlogic-c3: Add validations for ae and awb config Avoid invalid memory access if the zones_num is bigger than zone_weight.
This patch fixes the following smatch errors: drivers/media/platform/amlogic/c3/isp/c3-isp-params.c:111 c3_isp_params_awb_wt() error: buffer overflow 'cfg->zone_weight' 768 zone_weight' 768 zone_weight' 255 zone_weight' 255 <= u32max This vulnerability arises from improper validation of automatic white balance (AWB) and automatic exposure (AE) configuration parameters.
Specifically, the driver does not correctly check the number of zones against the allocated memory for zone weights, leading to invalid memory access. This can result in a buffer overflow, which may allow an attacker to corrupt memory and potentially impact system stability or integrity.
Red Hat severity: not rated. Weakness: CWE-787.
Red Hat lists Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected.
