Doc Text:
A flaw was found in the Linux kernel's `media: amlogic-c3` driver. 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.

Description OSIDB Bzimport 2026-08-10 12:36:29 UTC 
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 <= u32max
drivers/media/platform/amlogic/c3/isp/c3-isp-params.c:111 c3_isp_params_awb_wt() error: buffer overflow 'cfg->zone_weight' 768 <= u32max
